Mae Sai border crossing 17 March 2023.
Hi guys wanted to post this to see if it helps anyone.
I did the crossing on the date above and HAD NO ISSUES AT ALL.
I took the Green bus from CM bus terminal at 8am (470 THB one way which includes 7/11 fee ) It was full so if this is your only mode of transport don't leave it till the last minute to book.
Arrived at the border at 1:30pm
Was asked on the Thai side if I had vaccination cert which I did
Got stamped out and crossed the bridge as usual.
There is a small desk just before you get to the office to be stamped in and out of Burma
The lady took my passport and completed a form, all I had to do was sign it.
Then straight to the stamping office paid 500 THB, passport given back and back across the bridge.
Completed the arrival card and stamped back into Thailand.
Whole thing took around 15 minutes.
Even though they have the usual signs everywhere I myself and as far as I know everyone else were not asked to provide any kind of proof for re-entering.
Back to the bus terminal to catch the Green bus back to CM at 3pm. Plenty of time but it wasn't busy.
Both Thai and Burmese immigration officers were very freindly .
Hope this helps someone
