@Sabi ****
and it should have thai written on it that says that stamp was issued up until your insurance expires
AND
your eVisa should also have a remark that lists the expiration date of your insurance
The current entry stamp you're here on doesn't affect anything as far as getting back in, it's the validity of the VISA itself (which you say is good until Mar 19th 2025)
What messes you up as far as bouncing out and back to get a new year stamp is that single re-entry permit that is linked to the current entry you have, ๐
You come back in BEFORE the 14th Mar 2025 passes and you'll get stamped in only UNTIL that date ๐ฎ
You gotta let that re-entry permit expire and then you can enter the country on the currently valid OA eVisa (with the proof of a new year insurance)
