Thailand's 30-Day Visa Rule: How to Plan a Southeast Asia Trip Now

In short: UK, Irish, EU, US, Canadian, Australian and New Zealand passports now get 30 days visa-free in Thailand, down from 60. Any trip under four weeks is unaffected. It matters if you want more than 30 days in Thailand in one go, if your route crosses back into Thailand overland more than twice in a calendar year, or if you are volunteering for a month or more. Fly in, do Thailand first, then move on to Vietnam, Cambodia or Laos, and the rule barely touches you.

What changed on 15 September

Thailand ended its 60-day visa exemption on 15 September 2026. Passport holders from 60 countries and territories now get up to 30 days for tourism instead. That list includes the UK, Ireland, all 27 EU countries, the USA, Canada, Australia and New Zealand, so if you are reading this in English the chances are it covers you.

Two other parts of the package matter for backpackers. Visa-free entries through a land border are limited to two per calendar year, and the 30 days can be extended once, by another 30, at an immigration office. Everything else, from the Thailand Digital Arrival Card to the six months of passport validity, is the same as before.

This page is about planning a route around those rules. For the entry rules themselves, nationality by nationality, read our guide to whether you need a visa for Thailand.

How to count your 30 days

Count the day you land as day one. The stamp in your passport shows the last day you are allowed to stay, and that date is the one that counts, not your own arithmetic. Check it before you leave the immigration desk.

Then work backwards from your flight out. A 19-day tour leaves you 11 days either side of it. Arrive three days early to get over the jet lag, add a week on the islands afterwards, and you are at 29. That is fine, but it is also the point where a delayed flight or one more night on Koh Phangan tips you over.

Tip: Overstaying is not a paperwork problem you sort out at the airport. The fine is 500 THB a day up to 20,000 THB, and the FCDO warns that overstayers can be detained, deported or banned from coming back. If your plans are drifting past 30 days, extend before the stamp runs out, not after.

Immigration can also ask to see a ticket out of Thailand and around 10,000 THB in funds, and British travellers have been refused entry without them. A return or onward flight inside your 30 days answers both questions at once.

Fly in, do Thailand first, then move on

The simplest way to plan around the rule is to treat Thailand as one block. Fly into Bangkok, spend your time in Thailand in one go, then fly or cross out to the next country and do not come back. One entry, one stamp, no counting across visits.

It is how our longer trips already run. Backpacking Thailand & Vietnam and Backpacking Asia both spend their first 18 days in Thailand, from Bangkok down through Khao Sok and the islands and then up to Chiang Mai, before flying to Hanoi. The 30-day clock only runs for that Thai leg, so even with a few days in Bangkok before the start you are well inside it.

Vietnam then has its own rules. British citizens and a number of European nationalities can visit visa-free for up to 45 days, and everyone else uses the e-visa, which runs to 90. Our Vietnam visa guide has the detail.

The overland loop and the two-a-year limit

The classic backpacker loop goes the other way. Bangkok, out by land to Siem Reap for Angkor Wat, round through Cambodia or Laos, then back into Thailand by bus. It still works, but every time you come back over a land border on the visa exemption you use one of your two land entries for that calendar year.

Two is plenty for one loop. Where people get caught is the trip that crosses three times: out to Laos, back for the islands, out to Cambodia, back to fly home. The third crossing is the one that is refused. Flying in is not part of the cap, so if your route needs a third entry, make it a flight. Bangkok has short, cheap flights from Siem Reap, Phnom Penh, Vientiane and Luang Prabang.

Each new entry gives you a fresh 30 days, but do not treat that as a way to stretch your stay. Officers decide every arrival on its own merits, and someone who keeps leaving for a weekend and coming straight back is exactly who they question. If you want to be in Thailand for longer, get the visa that says so.

The neighbours each have their own entry paperwork, and none of it is the same as Thailand's:

• Cambodia: British travellers need a visa. Get the e-visa at least four days ahead, or a 30-day visa on arrival, paid in US dollars with a passport photo. Our Cambodia visa guide goes through both.
• Laos: a visa is needed too. Visa on arrival is available at many entry points and an e-visa can be applied for at least five days ahead. Either gives you 30 days.
• Malaysia: British travellers normally get 90 days on arrival, but you must submit the online arrival card before you travel.
• Vietnam: 45 days visa-free for British citizens, or an e-visa for up to 90.

Tip: Check your own passport against every country on the route before you book anything, not just Thailand. Sherpa lists the rules for each leg in one place.

Staying in Thailand longer than 30 days

There are two proper ways to do it, and which one suits you depends on how much longer you need.

Just over 30 days: extend once you are there

Enter visa-free, then apply for the 30-day extension at an immigration office before your stamp expires. The fee is about 1,900 THB, it is at the office's discretion, and it takes most of a morning, so do it in a town with an office rather than leaving it to your last day on an island. That gets you up to 60 days in total.

Six weeks or more: get a Tourist Visa before you fly

The Single-Entry Tourist Visa (TR) gives you 60 days from arrival, and it can be extended by a further 30 once you are in Thailand, for up to 90 days in all. Apply through the official Thai e-visa portal, or the embassy or consulate that covers you, well before you travel. Requirements and fees vary by where you apply.

For anything beyond 90 days you are into long-stay visas, which depend on your nationality and what you are doing. Speak to the Thai embassy before you book flights.

Volunteering in Thailand under the 30-day rule

Our Thailand placements are based in Hua Hin, and you can stay from one week to twelve. Volunteers enter as tourists: there is no special volunteer visa for these programmes, and you should say at immigration that you are travelling for tourism and joining a cultural, community-based programme. You must not take paid work.

Three weeks plus the recommended Culture Week sits inside 30 days. Anything over four weeks in total needs planning: the 30-day extension takes you to 60 days, and for two months or more the Tourist Visa before you fly is the cleaner option. If you are combining kindergarten teaching or the elephant project with a tour, count both together, because the stamp does not care which part of your trip is which.

Before you fly

• The TDAC. Every arrival needs the free Thailand Digital Arrival Card, filled in online within three days before you land. Ours explains it: TDAC required for entry to Thailand.
• Passport. Six months of validity from the day you arrive, and at least one blank page. A long overland trip uses pages fast.
• A ticket out. An onward or return flight inside your 30 days, or inside your visa if you have one.
• Insurance. Get cover that runs for the whole trip, not just the Thai leg. SafetyWing can be bought after you have left home.

If you are still deciding how long to give Thailand, our 10-day Thailand itinerary and north or south Thailand guides will help you size it, and the Thailand weather guide will tell you when.

Why book with Backpacking Tours?

We have run small-group trips through Thailand since 2013, and every one of them fits inside the 30-day rule with room to spare. Our longer Southeast Asia trips do Thailand first and fly on to Vietnam, so you enter once and never have to count a land crossing. Groups are 6 to 20, aged 20 to 45, with a guide, in-country transport and activities included, and a £250 deposit holds your place.
