How should I handle my 90-day reporting and NON-O visa extension in Thailand?

IMPORTANT REMINDER: Each immigration office is different. The policies for Kanchanburi may not be the same for Chiang Mai.

Does it make sense? No. But, it is what it is.

okay, people let's get this sorted.

Getting a NEW yearly extension of stay has NOTHING to do with your 90 day reporting (if you've been doing it before) and a new extension doesn't reset the 90 day reporting. You still do it when the receipt tells you it's due.

Here's a fool proof way to know with 100% accuracy IF your 90 day reporting date was 'reset' when you got a new yearly extension

IF you DID get a new 90 day report receipt with a new 90 day report date 3 months out they did reset your 90 day reporting

BUT

IF you DIDN'T get a new 90 day report receipt and still have the old one in your passport they did NOT reset your 90 day reporting

your 90 day report has nothing to do with when your next extension is due.

SO if you have a 90 day report due on Nov 8 you need to do that AND then apply for your yearly extension.

Most offices let you apply for a new extension when you have 30 days or less left on your stamp so you could do them BOTH at the same time you go file your 90 day report

Which immigration office? Are you still using Chiang Mai?

The 90 day reports and the one year extension of stay are separate documents and may not be in synch.
