Hi..just like to say... I have just been to Mae Sai for Border run/bounce... It's open ok, they will ask you for proof of vaccination (the 2 jabs) but not really a problem... It took me 5min In&Out and I paid $10.. But u can also pay 500 THB...
TLDR : Answer Summary
A recent user shared their experience of completing a border run in Mae Sai, Thailand. The procedure was quick, taking only about 5 minutes for an In & Out process. Travelers need to present proof of vaccination for two doses, but there were no significant issues. The cost of the border run was reported to be either $10 or 500 THB.
