Hello group!
I have a UK passport and was in Thailand a few months ago. I spent 60 days there in total, 30 days visa free + 30 days extension in Bangkok immigration office.
Would anyone know if I can re-enter Thailand say next week, and obtain another 30 day visa?
TLDR : Answer Summary
A UK passport holder who spent a total of 60 days in Thailand (30 days visa-free plus a 30-day extension) can likely re-enter Thailand and obtain another 30-day visa exemption. Most commenters agree that there should be no issues with re-entering within a short timeframe given this recent travel history. It is noted that entry by air allows for a 30-day visa exemption, which can typically be extended for an additional 30 days at an immigration office for a fee.
