hello - I am flying out of Bangkok on Tuesday morning to the US. When I have left the country in the past, I have needed to go to immigration to get a re entry permit plus pay a fee. Is this still needed ? If so, will I be able to obtain it at the airport ? ((flight leaves at 8am)
TLDR : Answer Summary
Yes, you need a re-entry permit to keep your extension of stay active while flying out of Bangkok. You can obtain this permit at Suvarnabhumi Airport, which has a re-entry counter open 24/7 located in International Departure 2. The fee is 1,200 THB at the airport. Alternatively, you can get a re-entry permit for 1,000 THB at the immigration office a day before your departure.
