US nationals who entered Thailand on a Visa waiver: How many 30-day Visa waiver extensions were you able to receive before having to leave the country for reentry? I'm on my 1st waiver extension (total 60 days) hoping for a second waiver extension to make 90 days.
TLDR : Answer Summary
US nationals entering Thailand on a Visa waiver can initially stay for 30 days, which can be extended once for an additional 30 days, totaling 60 days. However, further extensions beyond this typically require leaving the country and reentering.
