The 90 day report "resets" everytime you leave, as it is a report for those who STAY in thailand for 90 or more days. Leaving and returning will set it back to day 1
I have a feeling it's just not common as most teachers who are here already have the extension of stay and most situations probably don't have teachers leaving in the first 90 days 😅
Long story short been here 5 years on legitimate consecutive extensions of stay based on working... but in February of this year I had my first instance of losing a job prior to the contract finishing; forcing me to leave and return/remain here as a tourist just the past 3 months. Now I've found work again and should be able to secure the Non B without any issue. Have always been here legitimately, just the last couple months have required pop outs and since I live in Hatyai (Canadian nationality) going to Malaysia has been manageable.
I knew my previous "pop out & back in" via land border based on visa exemption was my last one allowed for this year, but if coming back with the NON-B is allowed, by land, I shouldn't have much to worry about.
Just to confirm: "a valid non-b visa" is that sticker they literally physically put in my passport at a neighbouring consulate ... right? That is then allowed at a land border crossing into Thailand because the 2 entries/yr. is only limited to entries based on exemptions, right? That makes sense and is very reassuring!
What difficulties to you forsee if I come back in by air? [Ideally I won't do that anyways because land borders are so much closer to where I live]
Yeah it makes no sense not to file it... because it costs nothing to do and will re-set when you come back. But not doing it could still result in a fine, so why not just file it?
