Any here with a US passport have ever received a 7 day extension after a 30 day extension on a 30 day tourist visa exemption?
An employee at this hotel thankfully phoned and confirmed that is possible (I had a flight scheduled to a town where a "super typhoon" hit), but I want to MAKE COMPLETELY SURE that getting that extra 7 days Thai visa extension won't affect any future interactions with Thai immigration.
Thanks in advance for answering if have had one of those!
TLDR : Answer Summary
The question concerns the possibility of a US passport holder obtaining a 7-day extension after a 30-day extension on a tourist visa exemption in Thailand. Responses indicate that while a formal 7-day extension does not exist, one might receive a stamp requiring them to leave Thailand within 7 days if their application for an extension is rejected. This could potentially affect future interactions with Thai immigration, as having such a stamp may complicate obtaining visas for other countries.
