What happens if I overstay my visa in Thailand?

Overstaying your visa in Thailand is an immigration offence and can result in fines, detention, deportation, and being banned from re-entering the country, depending on the length of the overstay and the circumstances. The longer the overstay, the more serious the consequences are likely to be.

What We See In Practice

I only overstayed for a few days. Can't I just pay a fine and carry on?

WHAT CLIENTS ASK US

Sometimes, but not always. If you voluntarily leave Thailand after a short overstay, you’ll usually just need to pay the overstay fine at the airport. However, if you’re caught by Immigration while overstaying, the consequences can be much more serious and may include detention, deportation, and a ban from re-entering Thailand.

Thailand imposes a fine of THB 500 per day for overstaying a visa, up to a maximum of THB 20,000, where the foreign national presents themselves voluntarily to Immigration before being arrested. However, if a person is found to be overstaying during an immigration inspection or police check, the consequences can be significantly more severe. In addition to the overstay fine, Immigration may detain the individual pending deportation and impose a ban on re-entering Thailand.

The length of the overstay also affects the immigration consequences. Foreign nationals who voluntarily surrender after a prolonged overstay may be banned from re-entering Thailand for between 1 and 10 years, depending on the duration of the overstay. Those who are arrested before reporting themselves can face even longer entry bans. For this reason, if you realise you have overstayed your visa, it is usually far better to address the issue with Immigration as soon as possible rather than waiting for it to be discovered.
