Hello United States passport here.
I entered Thailand on a 30 day visa exemption and then got a 30 day extension on that. Do I have an option to extend this again or is border run my only option? If I go to Laos for a few weeks or month I'll get another 30 day exemption no problem yes?
TLDR : Answer Summary
A U.S. passport holder entering Thailand on a 30-day visa exemption can extend the stay once for another 30 days but cannot obtain a second extension in sequence. The options are to do a border run to neighboring countries like Laos to obtain another 30-day visa exemption or apply for a 60-day tourist visa in Laos, which can be further extended for an additional 30 days.
