Thailand Visa Rules
Visa exemption, tourist visas and the extension run — what actually applies to most visitors
Most nationalities can enter Thailand visa-exempt for a set number of days on arrival, no paperwork filed in advance. The rules around exactly how many days, and what to do once that runs out, change often enough that treating any specific number as permanent is a mistake — always check the current allowance against your own passport before booking flights.
Quick facts
Visa exemption on arrival
Most Western, several Asian and a growing list of other passports get a visa-exempt stamp at immigration — no application, no fee, just a stamp in the passport. The exact day count has shifted more than once in recent years, so check the current figure for your nationality specifically rather than going by what a forum post said last year.
Tourist visas and extensions
If you want to stay longer than the visa-exempt window, a Tourist Visa applied for in advance at a Thai embassy/consulate gets you more days upfront, and a single extension is available at an Immigration office inside Thailand for a fee. Extension rules and the fee amount are set by Thai Immigration and worth confirming directly before relying on them.
Border runs and overstay
Leaving and re-entering purely to reset the visa-exempt clock (a "border run") is legal but has gotten less reliable — immigration officers can and do refuse entry to people who look like they're just cycling stamps. Overstaying is a fixed daily fine plus a real risk of a longer-term entry ban if it drags on; it's not worth treating casually.
Practical tips
- —Check your specific passport's current visa-exempt day allowance right before booking — this number has changed more than once in recent years.
- —A return/onward flight and proof of funds are occasionally checked at immigration — have them accessible, not just booked somewhere in your inbox.
- —If you're planning to stay months, look at the Tourist Visa route before you fly, not after — it's far easier to arrange in advance than to fix once you've already landed.
- —Don't rely on repeated border runs as a long-term strategy — immigration discretion on this has tightened.
