What is the Thailand immigration blacklist?
The immigration blacklist is a list of foreign nationals who are prohibited from entering Thailand. Blacklisting can result from overstay, criminal convictions, working without a permit, or other immigration violations. Blacklist periods range from 1 year to a lifetime ban depending on the severity.
What is 90-day reporting in Thailand?
Foreign nationals staying in Thailand for more than 90 days on a long-stay visa must report their address to immigration every 90 days. This can be done online, in person, or by mail. Late reporting incurs a fine.
What happens if I overstay my visa in Thailand?
Overstaying is a serious offence. You will be fined 500 baht per day of overstay (up to 20,000 baht). If caught, you may be detained and deported. Overstay of more than 90 days results in a 1-year blacklist; longer overstay periods result in longer bans.
Can a criminal case affect my immigration status?
Yes. A criminal conviction or even pending charges can result in visa cancellation, deportation, and blacklisting. It is important to address both the criminal and immigration aspects of your case with a qualified lawyer.
