I have a non b one year visa and wp - my visa expires on 21st March 18. It used to be possible to exit and re- enter a week or so before the expiry and get another 3 maths - with all the changes I'm not up to date - can anyone tell me if this is still possible please?
TLDR : Answer Summary
The possibility of exiting and re-entering Thailand shortly before the expiration of a Non-B visa to obtain an additional 90-day stay appears to still be valid, assuming you hold a multi-entry Non-B visa. Community members confirm that if your visa was issued by a Thai consulate abroad, you should be able to border bounce before the 'enter before' date on your visa, thus granting another 90-day stay.
