The excitement of a holiday is great, but planning an overseas trip always starts with the right travel documents. Whether it is a beach holiday in Asia, a city break to London or a business trip to the USA, it is essential to find out early which entry requirements apply to your destination country.
Do you need a traditional tourist visa that must be applied for in advance? Is an electronic travel authorisation enough (such as ESTA for the USA or eTA for Canada)? Or, within Europe, is your standard national identity card sufficient? Our guide and interactive checker provide the exact answers for your next destination.

Requirements vary considerably depending on your nationality and destination country. In principle, there are three scenarios:
National identity card: Fully sufficient within the Schengen Area and in many European countries.
Passport (without visa): For many long-haul destinations (e.g. Thailand, Japan), British tourists may enter visa-free for a certain period, but they still need a passport that is often required to be valid for at least 6 months at the time of entry.
Passport with visa / e-visa: For countries such as China, India or the USA, you must apply for a visa or electronic travel authorisation before travelling. If you forget, you will not be allowed to board the aircraft.

Entry checklist for long-haul travel
Passport validity: Will your passport still be valid for at least 6 months on the day of entry, and does it still have blank pages? (Be careful with emergency or temporary passports: these are not accepted everywhere.)
Visa / ESTA / eTA: Have you received approval for your electronic travel authorisation, and do you have a printed copy with you?
Return or onward ticket: Almost all countries outside the EU require proof on entry that you will leave the country again.
Hotel booking & finances: You may often need to show proof of your first night's accommodation or sufficient financial means at the border.
Vaccination requirements (yellow fever etc.): Do you have your international vaccination certificate with you if the country requires certain vaccinations for entry?
Case studies: when entry is refused
Example 1: The expired passport before Bali
Mark is looking forward to his holiday in Indonesia. At the check-in desk in Frankfurt, the staff member notices that his passport is only valid for another 3 months. Indonesia strictly requires 6 months. Outcome: Mark is not allowed to board. As this falls within his own responsibility, neither UK Regulation 261 (UK261) nor a standard travel cancellation insurance policy will help. The money for the flight is lost.
Example 2: Underestimating transit in the USA
The Weber family are flying from Munich via Miami (USA) to Costa Rica. Because they are not leaving the airport in Miami, they did not apply for an ESTA for the USA. Outcome: In the USA, there is no classic "international transit area". Every passenger officially enters the country and then departs again. Without an ESTA, the airline in Munich refuses boarding. Their connecting flight to Costa Rica is forfeited.
FAQ: common questions about visas & entry
How long must my passport be valid for?
For most non-EU countries, your passport must be valid for at least six months at the time of entry. Many countries also require that the passport has at least two blank pages for stamps and visas. Within the EU, a valid national identity card is often sufficient.
What is the difference between a visa and an eTA / ESTA?
A traditional visa often has to be applied for in advance through an embassy or online (as an e-visa), with the relevant processing time. ESTA (USA) or eTA (Canada), by contrast, are electronic travel authorisations for citizens of countries that are otherwise exempt from visa requirements (such as the UK). However, they must still be obtained online before departure.
Do I need a visa if I am only changing flights at an airport (transit)?
That depends heavily on the relevant transit country. In the USA, even for a pure transit without leaving the secure area, you must have an ESTA or transit visa. In many Asian or Middle Eastern countries, however, you may remain in the international transit area without a visa.
What happens if I arrive at the airport without a valid visa or the necessary documents?
Airlines usually check your documents at check-in or, at the latest, at boarding. If documents are missing, you will be firmly refused carriage because the airline could otherwise face substantial penalties at the destination and may have to cover your return transport. You will bear the full cost of the missed flight yourself.
