When you enter Thailand visa exempt (American), is there a fee for each 30 day extension? I believe you can extend 2 times, for a total of 90 days, correct?
TLDR : Answer Summary
When entering Thailand visa exempt, Americans can extend their stay for a fee of 1900 baht, but this extension can only be done once, allowing a total stay of 90 days. For a guaranteed 90-day stay, it is recommended to apply for a TR visa that allows an initial 60 days with an option to extend for an additional 30 days.
