Can I re-enter Thailand before my 45-day visa exemption ends if I go to Malaysia?

Good luck to the O/P, we are done (y)

@Sophie ********

one final time

you are allowed TWO visa exempt entries by land in a calendar year (Jan 1 to Dec 31)

there is NO official limit to them by air

you FLEW in to get the 45 day stamp you're on, so it didn't count against the two LAND entries you can get a year.

GO on your vacation to Malaysia and when you come back by land you'll get stamped in on a new 45 day visa exempt entry.

@Sophie ********

what you're not gonna do is LIVE here on back-2-back free entry stamps 😕

As people pointed out you can get two visa exempt entries by land in a calendar year (that's Jan 1st to Dec 31) then the count "resets" and you can get two more entries by land next year.

There is technically no limit to the number of them you can get by air, BUT as I said at some point you're gonna get pulled aside and asked WTH you're doing living here on free stamps and be 'encouraged' to get a real visa to stay here

Here's how a visa exempt entry works.

You got 45 days when you stamped in to thailand,

When you stamp OUT of thailand that entry stamp cancels.

Then when you return to thailand you get a NEW 45 day entry stamp.
