Hello... If one enters the Kingdom as a visa-exempt American National (now extended to 45 days) what are the possibilities for extension? Also, as much as I have explained about the drawbacks of overstay, not to mention costs, my friend still thinks it's a viable way to stay for 80 days. By my calculation that would add 14,000 baht to his trip, and the scarlet letter in the passport.
Thanks as always for your guidance.
TLDR : Answer Summary
American nationals entering Thailand visa-exempt are initially granted a stay of 45 days, which can potentially be extended for an additional 30 days at Thai immigration for a fee of 1,900 baht. However, staying beyond this period without an extension poses significant risks, including arrest and deportation, making it unadvisable.
