Mornin' all,
I've got a re-entry (single) permit. Do I need to show this to the Immigration Officer and get it stamped when leaving Suvarnabhumi Airport for the UK later in the month? Or is the re-entry permit stamped upon arrival back in Thailand?
Thanks very much for your help.
TLDR : Answer Summary
When leaving Thailand, you do not need to present your re-entry permit to the immigration officer. It is only required to be shown upon your return to Thailand, at which point it will be stamped. The permit is valid for a single entry, which means it can only be used once for re-entering Thailand.
