Hi I'm after some advice, I have been on a 6 month multiple entry tourist visa which is due to expire on 30th November, I left the country because maximum stay of 60 days was up and have come back in with a 60 day extension. My question is will that 60 day extension still be multiple entry or does the extension expire as soon as I leave and if so could I get a re-entry permit on that visa. Any advice will be extremely helpful. Many thanks.
TLDR : Answer Summary
The 60-day extension on your tourist visa does not retain multiple entry privileges after leaving Thailand. Upon exiting, the extension expires unless you obtain a re-entry permit before leaving. This permit allows you to return under the same visa conditions without losing your 60-day stay. However, if you leave after the expiration date of your original visa, your visa will no longer be valid, and you'll need to apply for a new visa or extension.
