So you pay 1"000THB on exit. If you're just a regular tourist, that isn't a big problem.

Yeah it's well known that foreigners get problems for overstaying but they are mostly people with a long history in Thailand.

If you arrive on the 1. December and fly out on the 1. January at 2am, you will go through immigration on the 31st December, so absolute no problem. At worst, you'll pay 500THB.

I think, we didn't have a military coup for a while 😜

Under the current constitution it doesn't really matter who won, overall, the army still stays in power.

Only if you made the first 90 day reporting at an Immigration Office.

After that it's very easy to do on-line and only takes a couple of minutes. Then it takes between a few hours and several days to get the approval notification.

@Anne ******

For immigration, a six months statement with the accompanying bank letter should be enough.

I always used my Bangkok Bank Branch in Tongsala without any problems. Was always done within minutes and costs 100THB

Correct.

Your 90 day reporting start fresh from your date of re-entry.

Sorry, my bad. Well in this case, you can apply for one 30 days extension of stay.

In an emergency, you could always apply for a second extension. Then you'll get a stamp saying "Extension Denied" and an order to leave the country within 7 days. You will also need to sign a form where you acknowledge that you understand the implications of overstaying those 7 days.

Not quite sure how anyone can give you advice, without knowing what kind of visa you want to extend.
