My first re-entry permit.. I live in Chiang Mai, Fly to BKK and stay overnight for a 6am international flight. My form/photo is all prepared for the permit. Should I go to Chiang Mai immigration (who just moved to a new location that I don't know well) and get it now or should I get it at the BKK airport at... 4am? And for that matter, are they even open?
TLDR : Answer Summary
A user is unsure whether to obtain their re-entry permit at Chiang Mai immigration or at Bangkok's Suvarnabhumi Airport before a 6am international flight. Comments indicate that the airport office is open 24/7, allowing for flexibility, but there is concern about the timing to ensure they do not miss their flight.
