Do I need a visa for Thailand?
No, not on any of the fourteen passports on this page. You do have to fill in the Thailand Digital Arrival Card, from three days before you arrive. You get a 30 day stamp on arrival: up to and including 14 September 2026 that was still 60. Since then the exemption covers tourism only, not a few days of work or business.
What is the difference between a visa and an arrival card?
A visa is permission to enter the country, and it usually costs money. An arrival card is a digital form where you say who you are, where you are sleeping and how long you are staying. It is nearly always free, but it is compulsory. Without a completed card you can still be stopped at check in or at the desk, even when you need no visa at all.
Why does it matter which passport I choose?
Because in three of these thirteen countries it changes the answer completely. In Vietnam a British, German, French, Spanish, Italian, Swedish, Dutch or Swiss passport walks in for 45 days, while an Irish, American, Canadian, Australian, New Zealand or Austrian passport has to apply for an e-visa before flying. In Laos a Swiss passport gets 15 days without a visa, and everybody else needs one. In Sri Lanka the travel authorisation has been free since May 2026 for forty countries, and Ireland is not one of them. Being in the EU is not the deciding factor, which is exactly why you should not assume.
Can I not just use one of those visa websites?
You can, but you pay two to five times as much for exactly the same document. Those sites rank at the top of Google because they pay for advertising. The real addresses end in the government's own country code, like gov.kh, gov.la and go.th. This page lists the official address for every country, so you can click straight through.
How long does my passport have to be valid?
Six months across virtually all of Asia. What those six months are counted from varies: some countries look at your arrival date, others at the day you leave. So take the last day of your trip and add six months to that. Japan is the only exception here: there your passport only has to be valid during your stay.
What happens if I stay longer than my visa allows?
You pay a fine per day, and it adds up fast. In Indonesia that is 1 million rupiah a day. Overstay badly and you risk deportation and a ban on returning. Worse still: your travel insurance can refuse to pay out if you were not legally in the country at the time. Extending is possible almost everywhere and is always cheaper than the fine.
Do I really need to bring cash for my visa?
For Laos, Cambodia and Nepal you do if you are sorting it on arrival. There is often no card machine at the border, and paying in local currency usually works out dearer because the rate is poor. Bring US dollars in clean, untorn notes. Damaged money gets refused.
Why is there nothing here for my passport?
Because we have not checked it for that passport yet. We copy visa rules straight from the official advice and never add anything of our own. If we are not certain, we do not put a number there but send you to the official source for your country instead. That is more annoying to read and a great deal safer to travel on.
Where can I check this myself?
With your own government, and this page links to it for all fourteen passports: pick yours at the top and the source at the bottom of the table changes with it. That is where these numbers come from. If their text and ours ever disagree, theirs wins, because visa rules sometimes change from one week to the next.
