Can anyone confirm the validity of this document?
Is it true that an American can extend their 30 day tourist visa FOR A SECOND TIME INSTEAD of using a land border crossing as this, and flying home to America, is becoming impossible?
TLDR : Answer Summary
Yes, an American can extend their 30-day tourist visa for a second time inside Thailand. All tourists with a 30-day visa exemption or a 60-day tourist visa can apply for an extension. However, to qualify, one must fulfill specific requirements, such as obtaining a letter from their embassy if travel restrictions apply.
