How to Prepare Your Documents for Travel Outside the EU

A trip outside the European Union isn't just a matter of the ticket and the hotel — it's also a stack of documents whose absence can end in being refused entry at the airport. This guide walks you through everything you need to prepare before you board the plane.

Passport — the foundation of every trip outside the EU

When you're planning a trip beyond the borders of the European Union, your national ID card stays at home. Whether you're flying to Thailand, the United States, Japan or Morocco, the only identity document honoured at borders outside the EU is a passport. It's a rule with no exceptions, though many travellers still hope they'll somehow manage. They won't. Airlines refuse boarding at check-in, so the problem appears before you've even left.

Simply holding a passport is only the beginning, however. Just as important — often more so — is how long it stays valid at the time of travel. Most countries outside the EU require a passport to be valid for at least 6 months from your planned date of return. Not from the date of departure — from the date of return. That means if you return on 15 September, your passport must be valid at least until 15 March the following year. This rule applies to Thailand, Indonesia, Vietnam, India, Kenya, Tanzania and dozens of other popular destinations, among others.

Some countries require only 3 months' validity after return — for example a number of African states and some Latin American countries — but it's safer to assume the 6-month version as standard. Before every trip it's worth checking the specific requirements on your government's official travel-advice pages, which are kept up to date and written for your nationality. Don't rely on a forum post from two years ago.

If your passport loses validity in the coming months, act ahead of time. A passport is issued by your national passport authority — in most countries you apply in person and need a current biometric photo, an existing ID document or previous passport, and proof of payment. Processing times and fees vary by country, but the broad pattern is the same everywhere.

An express service is usually available in justified cases — for example when travel is necessary for health, professional or family reasons — but it isn't guaranteed. It's also worth knowing that standard processing times stretch out in the summer season: queues at passport offices in July and August are far longer than during the rest of the year. If you're planning a summer trip, apply no later than March or April. Children's passports usually carry a reduced fee compared with an adult's.

A child's passport is a separate matter. In the EU, every child — even an infant — must hold their own passport. It's no longer possible to enter a child in a parent's passport, as it was over a decade ago. A child's passport is often valid for a shorter period than an adult's (frequently around 5 years for younger children), so check the rules in your country.

When applying for a child's passport, the presence of both parents or legal guardians is generally required. If one parent can't attend in person, written consent with a notarised signature is usually necessary. The absence of this document results in the application being refused — without exception. In situations where parents are divorced or separated and one of them doesn't agree to the child's passport being issued, a relevant court ruling is necessary. That's a process that can take weeks, which is why such matters are worth resolving well in advance.

A practical piece of advice to close: check the state of your passport today — regardless of whether you have a trip planned or not. Issuing a new document takes time, and fixing a mistake at the last minute costs far more in nerves and money than calmly applying a few months before travelling.

Visa — when it's required and how to get one

An EU passport is one of the stronger ones in the world — according to current rankings it allows visa-free or simplified entry to more than 180 countries. That's good news for travellers, because it means that for most popular tourist destinations you don't have to queue at an embassy in advance. But "visa-free" doesn't always mean "no formalities at all" — and that's where a misunderstanding begins that lands plenty of travellers in trouble every year.

Visa-free destinations for an EU passport

Visa-free entry means you can cross a country's border solely on the basis of a valid passport, without applying for any document beforehand. That's how entry works for Turkey (up to 90 days), most Latin American countries — including Mexico, Brazil, Argentina and Chile — as well as Georgia, Armenia, Serbia and Albania. In these places you simply land, show your passport at the border and walk through. If you're weighing up where to go, Turkey is one of those classic options worth comparing carefully against the alternatives, much as you would when deciding whether Bulgaria or Turkey works out cheaper and safer for a given trip — and Albania has quietly become a cheaper, safer alternative to some long-standing favourites. It's worth remembering, though, that even without a visa a border officer may ask about the purpose of your trip, a hotel booking or proof of sufficient funds for your stay — and they have every right to.

The situation looks entirely different for countries such as the United States, Canada, Australia or Japan. Formally, EU citizens can enter without a traditional visa stuck into the passport, but they must first obtain electronic travel authorisation — and this is the step many people underestimate or forget.

E-visas and travel authorisations — the modern alternative

Electronic travel-authorisation systems work on the basis of registering in advance in a given country's online system. They aren't a visa in the traditional sense — they don't require an embassy visit, a consular interview or a stack of documents — but they are mandatory, and without them you won't board the plane. The main systems an EU tourist will encounter are:

• ESTA (USA) — Electronic System for Travel Authorization; it costs around US$40 (US$40.27 since the 2025 increase from US$21), is applied for online, and is usually approved within minutes to 72 hours; valid for 2 years or until the passport expires; allows stays of up to 90 days
• eTA (Canada) — Electronic Travel Authorization; costs CAD 7; a similar procedure to ESTA; required when arriving by air, not for land entry
• ETA (Australia) — costs AUD 20; available through the Australian ETA app or via agents; allows stays of up to 90 days within 12 months
• e-visa Turkey — although EU citizens can enter Turkey without a visa, the e-visa is an option for those who want a document confirmed in advance; it costs the equivalent of around US$50
• ETA (United Kingdom) — since 2025 the UK requires an ETA from EU citizens (strictly enforced since early 2026); it costs £20 and is required on every entry

The key rule with electronic authorisations: apply only through the official government website of the country concerned. The internet is full of intermediaries who charge a multiple of the official fee for a service you can complete yourself in a few minutes. For ESTA the official site is esta.cbp.dhs.gov, for the Canadian eTA it's canada.ca, and for the UK it's GOV.UK or the official UK ETA app. Any other site offering "help" obtaining these documents is simply a middleman profiting from your inattention.

A traditional visa — stuck into the passport or issued as a separate document — still applies in many countries, above all in parts of Africa, South and Central Asia. Countries such as India, China, Russia (a destination that, for obvious reasons, has stopped being popular), Saudi Arabia or Sudan require a visa obtained before departure at an embassy or consulate. The procedure looks similar in every case: you complete a visa form, attach the required documents and submit the application in person or send it by courier.

The documents needed to submit a visa application differ by country, but a standard set includes:

• a valid passport with at least two blank pages
• a completed visa form (most often available online)
• a current biometric photo meeting the given embassy's requirements
• confirmation of a hotel booking or an invitation from a private individual
• confirmation of a flight booking or ticket purchase
• proof of sufficient funds for the stay (a bank statement)
• the visa fee — the amount depends on the country and visa type

As an example, it's worth looking at the US visa, which for many travellers is the first encounter with an extensive consular procedure. Most EU countries are part of the US Visa Waiver Program, which is why most tourists now use ESTA rather than a visa. However, people who have previously been refused entry to the US, who had immigration problems, or who plan to stay longer than 90 days still have to apply for a traditional visa. The fee for processing a US visa application is US$185 and is non-refundable — even if the visa is refused (and depending on the visa type, additional fees may apply). Waiting times for an interview slot at a US embassy can run from a few weeks to a few months depending on the season.

A visa refusal is a scenario worth bearing in mind. Embassies have no obligation to give reasons for a refusal, though they usually indicate the general category of the problem. The most common causes are insufficient funds, weak ties to your country of residence (no stable job, family or property), previous breaches of visa rules, or incomplete documentation. After a refusal you can apply again, but it's usually worth waiting and strengthening your documentation — simply submitting another application without any change in circumstances rarely produces a different result.

Travel insurance — what you really need

One of the most common mistakes travellers make when leaving the European Union is the belief that the European Health Insurance Card (EHIC) is enough in every situation. The EHIC works only within EU member states and a few associated countries such as Norway, Iceland, Liechtenstein and Switzerland. Outside that area the card is useless — and literally so. If you break a leg in Thailand, faint in New York or need emergency surgery in Kenya, the medical bills fall on you alone. And those bills can be astronomical — hospitalisation in the USA can cost tens of thousands of dollars for a few days, and medical repatriation to your home country is an expense of the order of €25,000–35,000 and more.

Good travel insurance isn't a cost to be optimised by buying the cheapest policy from a random comparison site. It's a document that, in a crisis, decides whether you return home in one piece and free of debt, or with months of credit to repay for treatment abroad. Before choosing a policy, it's worth knowing what to look for and what the individual clauses in the terms and conditions actually mean in practice.

What to look for in a policy

The first and most important parameter is the sum insured for medical costs. This is the maximum amount up to which the insurer will cover your medical bills. For trips to Eastern Europe or North Africa, a policy with a sum of €25,000–50,000 is usually enough. For trips to the USA, Canada or Japan the minimum sensible sum is €100,000, and sensible travellers choose policies with a sum of €250,000 or higher. Medical prices in the United States are so high that lower sums stop having any practical meaning the moment a serious hospitalisation is involved.

Equally important is the repatriation clause — cover for the cost of transport home in the event of serious illness or accident. This isn't about an ordinary plane ticket, but specialist medical transport with staff on board, which when needed costs more than many a used car. A good policy includes repatriation with no limit or with a very high limit — check this clause before buying, because cheap policies often restrict it or exclude it for certain conditions.

Beyond treatment and repatriation, it's worth paying attention to baggage insurance (covering loss, theft and damage), third-party liability abroad (personal liability — when you unintentionally damage someone's property or injure someone), and cover for trip cancellation costs. The last is useful when, for reasons beyond your control — illness, accident, the death of a loved one — you can't fly as planned and lose pre-paid tickets and hotel bookings.

Pay attention too to the exclusions of liability — the situations in which the insurer won't pay a cent. Standard exclusions cover incidents under the influence of alcohol or drugs, self-harm, chronic illnesses existing before the trip (though these can be added as an extension), and — and here the most common problem appears — activities considered risky.

Sports and activities — the traps in the small print

If you're planning anything more than lying on the beach, the question of activities in your policy becomes crucial. Most standard travel insurance doesn't cover accidents during extreme sports — and the definition of "extreme" can be surprisingly broad. Some insurers count diving, kitesurfing, high-mountain trekking, quad biking, rafting or even rock climbing in this category. If you're planning one of these sports and don't check the small print, you can be left with a treatment bill despite holding a policy.

The solution is to extend the policy to include high-risk sports — practically every insurer offers such clauses. They cost more, but they give real protection. When buying insurance, describe exactly what you plan to do on the trip — dive, walk in the mountains, ride a motorbike — and make sure the agent or system confirms those activities are covered. A verbal assurance that "everything is included", with nothing to reflect it in the policy, has no value whatsoever at the moment of a claim.

The cost of travel insurance depends on several factors: the destination, the length of the trip, the age of the insured and the scope of cover. For a week-long trip to Thailand, a standard policy for an adult usually costs around €20–45. The same trip with a high-risk sports extension and a higher sum insured is an expense of the order of €35–80. A two-week trip to the USA with a sensible sum insured (€100,000+) costs from €45 to €115 depending on the insurer and scope. In the context of the total travel budget these are marginal amounts — but the difference between having and not having good insurance can mean a financial catastrophe.

It's also worth knowing that some premium credit cards offer travel insurance as a benefit — for example Visa Infinite, Mastercard World Elite or selected bank products. Before buying a separate policy, check exactly what your card offers. Card insurance often has lower sums and more exclusions than dedicated travel policies, however, so for exotic or long trips it's better to buy separate cover.

Finally, a practical rule: save the insurer's helpline number in your phone and note it on a card kept separately from your documents. In a crisis — after an accident, in a hospital lobby in a foreign country — searching for your policy number in your email inbox takes time you may not have. A good insurer offers a helpline open around the clock, seven days a week, in a language you speak. It's one of the parameters worth checking before buying — and one that has real value when choosing a policy.

Financial documents and payments abroad

The question of money on a trip outside the EU is a subject where many people lose hundreds needlessly — not through theft, but through lack of knowledge. Currency-conversion commissions, unfavourable rates forced by cash machines, cards blocked by banks detecting "suspicious" transactions in an exotic country — these are the realities anyone who doesn't prepare properly will encounter. The good news is that avoiding these problems doesn't require complicated steps — just a few decisions made in advance.

Let's start with cash. The question "should I take cash, and how much" has no single answer — it all depends on the destination. In countries such as Japan or Germany, cash is still widely used and in many places the only accepted form of payment. In Thailand, Vietnam or Indonesia, paying cash in the local currency is not only convenient but often cheaper — many small restaurants, markets and local transport don't take cards at all. In Australia, Canada or Scandinavia, on the other hand, cash is almost redundant — cashless payments work almost everywhere, even in small shops and at little markets. Before travelling, check the specifics of the particular country and region you're heading to.

If you decide to take cash, the question of exchange arises. Exchange offices at airports and in hotels offer decidedly the worst rates — margins there reach into double-digit percentages, which on the equivalent of €250 exchanged means a real loss of €20–35 or more. You'll find far better rates at exchange offices in the city centre — both at home before travelling and in the destination country. It's worth exchanging a small amount before you leave so you have local currency for the first hours after arrival (taxi, food, water), and exchanging the rest on the spot or withdrawing it from a local cash machine.

Multi-currency cards are a solution that has completely changed how people manage money on the road in recent years. Revolut and Wise (formerly TransferWise) offer cards that convert currencies at the mid-market rate — the interbank rate, with no added margin. In practice this means that paying by Revolut card for dinner in Bangkok, you'll pay exactly the current market rate, with no hidden commissions. Compared with an ordinary bank card, which typically adds 2–3.5% commission on every currency transaction, the savings over a two-week trip can run to a few hundred euros.

Using cards abroad brings one more trap: DCC, or Dynamic Currency Conversion. This is a mechanism where the payment terminal or cash machine offers to convert the transaction into your home currency — with a polite message that "you can see exactly what you're paying". In reality the rate applied with DCC is far worse than your bank's rate, and the bank will take its commission anyway. Always choose to pay in the local currency — that's the only correct answer to the terminal's question "which currency do you want to pay in?"

The question of notifying your bank about a trip has lost importance compared with how necessary it was a few years ago. Most modern banks use transaction-analysis systems that assess risk themselves and block cards on foreign payments less often than before. Even so, for trips to more exotic countries — sub-Saharan Africa, Central Asia, less-visited parts of South America — it's worth notifying your bank in advance. A few minutes via the mobile app or helpline is enough. A blocked card in a foreign country, with no way to withdraw cash and no alternative payment method, is one of the more stressful travel scenarios.

A good practice is to take at least two payment cards on a trip, stored separately. If one is stolen, lost or blocked by the bank, you have an instant backup. One card should be a multi-currency card or one with a low foreign-transaction commission, the other a standard bank card as a reserve. Store them in different places — one in your wallet, the other deep in a backpack or hotel safe.

It's also worth keeping digital copies of your financial details: card numbers, the phone numbers for cancelling cards, your bank account number. The point isn't to store full card details (never do that anywhere in the cloud), but to have access to the contact numbers that let you block a card in case of theft. Most banks allow a card to be blocked instantly via the mobile app — check that this option works in your app before you fly.

Copies of documents and securing your data

A lost or stolen passport abroad is one of those scenarios nobody wants to think about while planning a holiday — which is precisely why most people aren't prepared for it. Yet a quarter of an hour before departure is enough to keep the situation under control in case of problems, rather than standing helplessly at a police station in a foreign country with no documents and no idea what to do next. The principle is simple: every important document you take on a trip should exist in at least two copies — one on paper and one digital.

The list of documents worth copying before a trip includes your passport (the photo and personal-details page), your visa or confirmation of electronic travel authorisation, your insurance policy with the insurer's contact number, payment cards (only the last four digits and the cancellation phone number — never the full details), hotel and flight booking confirmations, and — when travelling with children — their passports and any parental consent. Keep the paper copy separately from the originals — for example in a different pocket of your backpack, in checked baggage when you have the originals on you, or leave a copy with someone you trust at home.

A digital copy is the second pillar of protection. The simplest solution is to send scans of your documents to your own email address — you'll have access from any device with internet, anywhere in the world. The alternative is storing scans in the cloud: Google Drive, Dropbox or iCloud all work equally well. Some travellers use dedicated apps for managing travel documents, such as TripIt or App in the Air — they let you keep all your bookings, documents and contact details in one place.

An important rule about digital copies: don't keep scans of documents in your phone's photo gallery with no protection at all. If the phone is stolen along with your passport, the thief gains access to all your data at once. Keep scans in a password-protected folder or in an app requiring authentication. Access to the phone itself by PIN or fingerprint is the minimum — it's not enough if the device falls into the wrong hands with the screen unlocked.

Emergency documents and the journey home

If, despite all precautions, your passport is lost or stolen, act according to a set plan. Panic is a poor adviser — and the good news is that your country's diplomatic missions abroad exist precisely to help in such situations. As an EU citizen, you have an additional safety net: if your own country has no embassy or consulate in the country you're in, you have the right to consular protection from any other EU member state's embassy on the same terms as its own citizens.

• Report the theft to the police — go to the nearest police station and obtain written confirmation of the report (a police report). Without this document the insurer won't pay compensation, and the consulate won't be able to help efficiently.
• Contact your embassy or consulate — find the address and phone number of the nearest diplomatic mission of your country (or, if it isn't represented, another EU country). Phone or go in person — this is the first and most important institution that can help you.
• Apply for an emergency travel document — diplomatic missions can issue an emergency travel document valid for the journey home. EU citizens can be issued an EU Emergency Travel Document, including by another EU country's embassy where their own isn't represented. It's usually issued within 1–3 working days, though in urgent cases the procedure can be sped up.
• Keep a copy of the police report — you'll need it to apply for a new passport after returning home and for any insurance claims.
• Inform your insurer — if you hold a policy covering loss of documents, report the incident as soon as possible. Many policies require notification within 24–48 hours of discovering the loss.

An emergency travel document is a single-use document issued by a diplomatic mission solely for the purpose of returning home or, in exceptional circumstances, continuing a journey. It isn't a full passport — it doesn't entitle you to cross every border and doesn't replace an identity document in the longer term. After returning home you should apply for a new passport as soon as possible.

For crisis situations abroad, it's worth knowing that most foreign ministries run a 24/7 consular emergency line — find yours and save it in your phone before you travel. From abroad you can call it for help establishing where the nearest diplomatic mission is and what to do in a specific situation. National digital ID apps, useful at home, generally don't replace a passport abroad, though they may help when contacting your consulate.

A separate issue is keeping documents safe during the trip itself. In hotels with a safe — use it. Most hotel safes are secure enough for a passport and some extra cash, though it's worth knowing that they usually aren't insured by the hotel, and in the event of a break-in the hotel takes no responsibility for the contents. In places without a safe, consider a travel money belt or a special document pouch worn under your clothes — effective protection against pickpockets in a tourist crowd. Don't leave a passport unsecured in a hotel room, especially in countries with a higher risk of theft.

It's also worth remembering one practical rule: in many countries you don't have to carry the original passport with you at all times. Local law varies, but in most popular tourist destinations a copy of the passport is enough for identification purposes during everyday sightseeing. Leave the original in the hotel safe and carry a photocopy or a photo of the document on your phone. This minimises the risk of losing the original to theft or in a crowd.

Health documents and vaccinations

When planning a trip to exotic countries, most people focus on attractions, hotels and budget — and leave the question of health to the last moment, or ignore it entirely. That's a mistake which, in extreme cases, can end in being refused entry at the border or a serious illness in the middle of the trip. Some countries treat vaccinations not as a recommendation but as an absolute condition of entry — and there's no room here for negotiation or pleading that "I didn't know".

Health requirements on entry concern above all yellow fever — a viral disease transmitted by mosquitoes, endemic in parts of sub-Saharan Africa and South America. Countries such as Ghana, Uganda, Kenya, Cameroon, Angola and Brazil require travellers arriving from, or passing through, risk areas to present a valid International Certificate of Vaccination — commonly called the yellow card. This document is issued by a vaccination centre after the vaccine is given and is valid for life (until 2016 a 10-year validity applied, which was then abolished). The absence of the certificate on entry to a country requiring yellow fever vaccination can result in refused entry or compulsory quarantine at the border.

Mandatory vaccinations are only the tip of the iceberg, however. A far broader list covers recommended vaccinations — not legally required, but advised by travel-medicine doctors because of the risk of illness in a given region. Recommendations vary by destination, planned travel style and the traveller's health. Example destinations and the associated recommended vaccinations:

• Southeast Asia (Thailand, Vietnam, Cambodia) — typhoid, hepatitis A and B, Japanese encephalitis for longer stays outside resorts, rabies for active contact with wildlife
• India and Nepal — typhoid, hepatitis A and B, rabies, Japanese encephalitis, meningococcal disease for trips to pilgrimage areas
• Sub-Saharan Africa — yellow fever (often mandatory), typhoid, hepatitis A and B, meningococcal disease, rabies, cholera for humanitarian trips
• Latin America — yellow fever (depending on the region), typhoid, hepatitis A, rabies for contact with wildlife
• Middle East — meningococcal disease (mandatory for the Hajj pilgrimage to Saudi Arabia), hepatitis A and B

Where can you check current requirements and recommendations? The most reliable sources are the World Health Organization database (who.int), your national public-health authority, and your government's travel-advice pages. It's also worth consulting a travel-medicine doctor — a specialist who will assess your health, vaccination history and planned route, then advise the optimal vaccination schedule. Travel-medicine clinics operate in most larger cities, often attached to infectious-disease hospitals. And because exotic destinations bring their own everyday health risks, it's worth reading up in advance on practical matters like how to handle water in exotic countries without stomach trouble.

An important timing point: some vaccinations require several doses given at weekly or monthly intervals, and full immunity appears only after the schedule is complete. The rabies vaccination consists of three doses given over a month. The Japanese encephalitis vaccination is two doses 28 days apart. If you're planning an exotic trip, a visit to a travel-medicine clinic should take place at least 6–8 weeks before departure — and ideally earlier.

Medicines in your luggage — what not to forget

Carrying medicines abroad is an issue that surprises many people. At home you can buy over the counter many preparations that in other countries are controlled substances — and vice versa. Some medicines available on prescription at home are completely banned in certain countries, which can mean serious trouble at the border if you don't have the right documentation. For the same reason it's worth being aware of the wider category of items you can't bring on a plane before you pack.

If you travel with regular medication — for high blood pressure, diabetes, thyroid conditions, asthma, epilepsy or other chronic illnesses — take a doctor's note in English confirming the diagnosis and the need to use the specific preparations. The document should contain the international (not just brand) names of the medicines, the dosage, and the doctor's stamp and signature. Some countries — particularly in the Middle East, East Asia and certain African states — carry out baggage checks for psychoactive substances and strong painkillers. Tramadol, codeine, strong benzodiazepines or methadone may be treated as banned substances without proper medical documentation.

For medicines requiring storage at a specific temperature — such as insulin — you need to plan transport with appropriate cooling equipment and check whether the hotel has a fridge. Airlines usually allow insulin and syringes in carry-on baggage on presentation of a doctor's note, but it's worth confirming this with the specific carrier before departure. Rules differ between airlines and can change.

Beyond regular medication, it's worth packing a basic travel first-aid kit suited to the destination. For a trip to Southeast Asia or Africa you'll need anti-malarial medication (prescription-only, selected by a travel-medicine doctor for the specific region), preparations for traveller's diarrhoea, antiseptics and plasters. For a trip to high mountains — altitude-sickness medication. For a stay in tropical countries — effective repellents with a high content of DEET or icaridin, which genuinely protect against the mosquitoes that carry malaria, dengue and other diseases. Preventive supplies bought before the trip are usually cheaper and better matched to your needs than those bought in a rush on the spot.

Health documentation, like the rest of your travel documents, should exist in a copy. Scan your vaccination card and doctor's notes and send them to your email address or save them in the cloud. Keep the originals in a safe place — ideally with your passport, but separately from cash and payment cards. Losing your vaccination card abroad is a serious problem, especially when returning through a country requiring proof of yellow fever vaccination — without the document you may be quarantined or sent back on the next plane.

Documents when travelling with children

Travelling with children outside the European Union involves an extra layer of formalities that parents often only learn about at the airport — at the worst possible moment. The border services of many countries treat the travel of minors without both parents with particular attention, and procedures designed to protect children from parental abduction are applied rigorously. The absence of the right documents can result in a child being denied boarding — no matter how obvious your situation seems to you.

The first rule is simple and admits no exception: every child travelling outside the EU must hold their own passport. It's not possible to enter a child in a parent's passport — that practice was abolished across the EU years ago. A child's passport is issued exactly as for an adult — at the passport authority, in person, on payment of a fee (usually reduced for children). The document is valid for a shorter period than an adult's in many countries. When applying, the presence of the child and both parents or legal guardians is generally required — the exception being where one parent is abroad or has been deprived of parental rights.

A child's passport is subject to the same validity rules as an adult's — in countries requiring a minimum of 6 months' validity after the date of return, that rule applies to the youngest travellers too. It's worth bearing in mind, especially for younger children's passports, which have a shorter validity period and need renewing more often.

Parental consent — how to write it

If a child is travelling with only one parent, there's a real risk of problems at the border — both leaving the EU and entering the destination country. Border guards have the right to ask about the other parent's consent and to verify that the child's travel raises no concerns. Destination countries, particularly Mexico, Brazil, Argentina, the Dominican Republic and the United States, have established verification procedures applied when minors cross the border without both parents.

Parental consent should be a written document, translated into English (or the language of the destination country), with the absent parent's signature notarised. The content of the consent should include: the child's full name, their passport number, the full name of the accompanying parent, the destination country or countries, the travel dates, and a clear statement that the absent parent consents to the child's trip. A good practice is to attach a copy of the absent parent's passport — additional confirmation of the document's authenticity.

A notarised signature can be obtained from any notary, usually for a modest fee. Some countries additionally require an apostille — a stamp confirming the authenticity of an official document internationally. An apostille for notarised documents is obtained from the designated authority in your country (often the foreign or justice ministry). It's worth checking in advance whether the destination country belongs to the Hague Convention and whether an apostille is required — you'll find this information on your foreign ministry's site or at the destination country's embassy in your country.

If a child is travelling alone — for example flying to grandparents abroad or going to a language camp — the formal requirements are even more rigorous. Most airlines have separate procedures for unaccompanied minors (UM), which include, among other things, designating the person collecting the child at the destination airport and the parents signing the relevant documents at check-in. The details differ between carriers, and it's worth asking about them directly when buying the ticket.

The situation is particularly complex where one parent has died, is unknown or has been deprived of parental rights. In such cases you need to bring the relevant documents confirming the circumstances — a death certificate, a court ruling depriving the parent of parental rights, or a ruling granting sole parental authority. The absence of these documents at the border can result in being held and lengthy explanations with local immigration services.

The situation is similar for blended families, adoption and foster care. If a child has a different surname from the accompanying adult, it's worth bringing a document confirming the relationship — the child's birth certificate, an adoption ruling or a foster-care certificate. At the border, a difference in surnames can be a source of questions, and the lack of an explanation a source of delays.

A practical piece of advice for any parent planning a trip with a child: contact the destination country's embassy in your country and ask directly what documents are required when a child travels with one parent. Requirements differ between countries and change over time — current information from the embassy is more reliable than anything read on an internet forum from two years ago. A few minutes' conversation with an embassy employee can save hours of stress at the airport.

Finally, take care of the same thing as with adults' documents: scans of the child's passport and the parental consent should go to your email address or the cloud before departure. A lost child's passport abroad is an even more complicated situation than a lost adult's — the consular procedures are similar, but the waiting time and required documentation can be more extensive. The better prepared you are, the more smoothly any consular intervention will go.

Pre-departure checklist — what to check on the last day

The day before departure is when most travellers pack a suitcase and check they haven't forgotten the phone charger. The documents, meanwhile, lie somewhere in a drawer and land in the bag at the last minute — unverified, dates unchecked, with no certainty that everything is complete. And that's exactly when, at the airport gate, it turns out the passport expires in four months, the visa is in a different name, or the ESTA confirmation was issued with the wrong passport number. The last day before a trip is not the time to gather documents — it's the time for their final verification. Gathering should be done much earlier.

The checklist below covers everything worth checking in the last 24 hours before departure. Go through it point by point — ideally physically setting each document aside after verification, so you're sure nothing slipped through.

• Passport — check the validity date (a minimum of 6 months after the planned return date), make sure the details are legible and the document isn't damaged; a badly worn passport or one with a torn cover may be rejected at the border
• Visa or electronic travel authorisation — verify that the visa is valid on the day of entry and that the details on it (first name, surname, passport number) match those in the passport; for ESTA or eTA, check the authorisation status in the system
• Flight tickets — print or save in your phone the booking confirmation with the PNR number; check departure and arrival times, the airport name (some cities have several airports) and the online check-in requirements
• Hotel and accommodation bookings — prepare confirmations for every night's stay; some countries require a booking to be shown on entry as proof of accommodation
• Insurance policy — check the policy's validity dates, make sure it covers the destination country and planned activities; save the insurer's emergency number in your phone
• Payment cards and cash — check the cards are valid and unblocked for foreign payments; make sure you have at least two cards and an appropriate amount of cash in the local currency for the first hours after arrival
• Document copies — verify that paper copies are packed separately from the originals; check that scans have reached your email or the cloud and are accessible from your phone
• Health documents — for trips requiring vaccinations, take your vaccination card or International Certificate of Vaccination; for regular medication, make sure you have a doctor's note in English with you
• Child's documents — if travelling with a child, check their passport, and when travelling with one parent, the completeness and currency of the notarised parental consent
• Emergency numbers — save in your phone your foreign ministry's consular emergency number, the number for cancelling payment cards and the insurer's helpline number

A separate matter is verifying the destination country's current entry policy. Entry rules change — sometimes from one day to the next, especially in politically unstable regions or in response to epidemic situations. Your government's travel-advice pages are updated on an ongoing basis and contain consular warnings worth reviewing a few days before departure, not just at the moment of buying the ticket.

It's also worth contacting your bank if the trip involves a less popular destination. Although notifying the bank is no longer as universally required as a few years ago, for trips to countries with a higher fraud risk or to regions rarely visited, one call or app message can prevent an unnecessary card block in the middle of the trip. It takes literally a minute and eliminates a serious risk. While you're getting your money in order, it's also a good moment to look at the broader picture of travel costs — there are plenty of clever ways to lower flight ticket prices that free up budget for the things that matter on the ground.

As for apps that genuinely make managing documents on a trip easier, it's worth having a few tried-and-tested tools on your phone. Google Photos or Apple Photos with cloud sync switched on provide an automatic backup of document photos. TripIt aggregates all your bookings in one place once confirmations are forwarded to a dedicated email address. Revolut or Wise let you manage a multi-currency card and freeze it instantly in case of theft. A national digital ID app doesn't replace a passport abroad, but it stores your home identity documents and can be useful when contacting your consulate.

At the very end — one rule that ties together all the previous ones: travel documents aren't a formality but the foundation of every trip outside the EU. A ticket can be bought at the last minute, a hotel booked from a phone at the airport, and a suitcase packed in half an hour. But you won't issue a passport with tomorrow's expiry date overnight, you won't get a visa to China in a week, and you won't obtain notarised parental consent on a Saturday afternoon before a Sunday departure. The earlier you start assembling your documents, the more calmly you'll be able to enjoy the trip — from the first day of planning right through to your return home.
