I am going to Bangkok on 1st Oct with single entry tourist visa and then going to Siem reap on 4th Oct from DMK airport and will return back BKK on 7th. My question is whether I can get the re-entry permit at DMK airport and how long before I need to reach airport to get that? Note that my flight time is at 1:30 PM.Also, If i somehow miss to get the re-entry permit then can I get another single entry tourist visa at BKK airport when I will return at 7th?
TLDR : Answer Summary
The post discusses travel plans from Bangkok to Siem Reap and inquiries about obtaining a re-entry permit at DMK airport. Key points include the ability to purchase a re-entry permit (1,000 THB) at the airport or the immigration office, recommended arrival times (2-3 hours before flight), and options for obtaining a Visa on Arrival (VOA) if the re-entry permit is not secured. Comments clarify that the individual is likely an Indian citizen, eligible for a VOA; however, a single-entry tourist visa would become void once leaving Thailand.
