What you should know
An overstay is any day spent in Thailand after your permission to stay ends. Fines are set by law, and longer overstays can lead to a ban on re-entry. Acting early \u2014 before you are stopped or reach the airport \u2014 keeps more options open.

Frequently asked questions
How are overstay fines calculated?
The official fine is THB 500 per day, capped at THB 20,000. Long overstays can also lead to a re-entry ban.
Will I be banned from Thailand?
Longer overstays can lead to a re-entry ban, especially if you are caught rather than surrender voluntarily. The length depends on the overstay period.
Can I fix an overstay without leaving?
In some cases a new extension or change of visa is possible after the fine is paid. It depends on your situation and the local office.
What should I do first?
Gather your passport and entry stamps and get a status review before going to Immigration or the airport.
