Overstay Clearance If a foreigner does not leave Thailand by the expiration date on their visa or on their permit to enter the Kingdom, they are considered to be in the country illegally. They will then be required to pay a fine when leaving Thailand. The fine amounts to 500 baht per day of overstay, up to a maximum of 20,000 baht. A short-term visa that has expired can be extended after the fine for overstay is paid, but the extension period granted is reduced by the number of days of overstay. To avoid a fine, the application to extend the visa must be made no later than the next working day after the expiration date of the visa. Foreigners overstaying their visa by more than 200 days may be incarcerated in the Immigration Detention Center before being deported. If a foreigner is arrested and found to not have a valid visa, the person is considered as being in the country illegally and faces a significant fine as well as deportation.
