For US Citizens on the 45 day visa exempt for the first time (via air), is it correct we can only do 2 border runs per calendar year to get additional 45 day visa exempt renewals? I'm seeing mixed answers online. Thanks
TLDR : Answer Summary
US citizens can perform two land border runs per calendar year to renew the 45-day visa exemption. There is no official limit on air entries, but the actual experience may vary depending on the immigration officer. Note that the 45-day exemption is set to revert to 30 days after March 31, 2023, but travelers can extend their stay by 30 days at a Thai immigration office for a fee.
