What Are the Differences Between Obtaining a Re-Entry Stamp at the Immigration Office and the Airport?

The main differences between getting a re-entry stamp at the immigration office versus at the airport are the hours of operation and potential fees. The immigration office is open only during business hours, while airport counters are available 24/7. At Suvarnabhumi Airport, there's a 200 baht service fee at a special counter unless you come prepared with forms and copies. Other airports may not have this fee, and you can also obtain a multiple entry permit at the airport without issues.
