Short answer: Since 15 September 2026, travelers from 60 countries and territories (including the US, UK, EU, Australia, Japan, India and most of ASEAN) enter Thailand visa-free for 30 days, for tourism. Others may use Visa on Arrival or need an e-Visa in advance. Everyone, by air, land or sea, completes the digital arrival card (TDAC) online before arriving.
The 3 main entry categories
How you enter depends mainly on your passport. Broadly there are three groups.
| Route | Example nationalities | Max stay | What you do |
|---|---|---|---|
| Visa exemption | US · UK · EU · Australia · Japan · India · most of ASEAN | 30 days (90 for South Korea, Brazil, Argentina, Chile, Peru) | Just a passport + the TDAC form |
| Visa on Arrival | A few nationalities (e.g. Azerbaijan, Belarus, Serbia) | ~15 days | Apply at the border, ฿2,000 fee + photo |
| e-Visa required | Nationalities not in the two groups above | Depends on visa type | Apply online on the official e-Visa site before flying |
Rules change often — check the official source
The number of days and the list of visa-exempt nationalities can change yearly. Before you travel, confirm with a Thai embassy or the Thai government e-Visa website. Do not rely on old blog posts alone.
What is the digital arrival card (TDAC)?
Thailand has moved from the paper TM6 to the Thailand Digital Arrival Card (TDAC) — a free online form every foreign visitor completes before arriving, whether by air, land or sea. Fill it in within the 3 days before you arrive and keep the confirmation to show at the border; it speeds up immigration.
- It is free — beware fake sites that charge a fee; use only the official Immigration Bureau website
- Have your passport number, flight number and first-night address ready
- It applies at land borders and seaports too, not only airports
Staying longer & extensions
If you want to stay longer, visa-exempt visitors can extend once, by up to 30 days, at an immigration office (฿1,900; the officer decides). Anyone planning a long stay, work or study should get the correct visa type from the start. Never overstay — there is a daily fine and it can affect future entries.
