Can I submit my first 90-day report by post after receiving a one-year extension of stay in Thailand?

There always is confusion about whether getting a new extension resets the 90 day reporting count down clock or not. Here's how you can tell with 100% accuracy if it does or doesn't at your office when you get a new extension

IF they hand you a new 90 day reporting receipt (the one with the bar code and a new 90 day report date on it) they DID reset the 90 day reporting count down clock :P

IF they DON'T hand you a new 90 day reporting receipt they DID NOT reset the 90 day reporting count down clock and you report like normal when you're current receipt tells you

brings up a good point (y) IF this isn't your very FIRST yearly extension and you were doing 90 day reporting before this extension the 90 day report date doesn't change when you get a new year extension.

It's only the very FIRST extension you get that starts the 90 day clock (and where they usually put that paper in your passport)

We you on an extension that was already doing 90 day reporting BEFORE this year extension based on marriage

?

I have successfully completed an online report after an extension of stay, and the timeline I used was based on my prior appointment or due date for 90 day reporting, with no change due to the date of my extension to stay. I have subsequently completed one 90 day report via EMS post, which I mailed 10 days before that due date, which worked fine.

Do a report before your previous visa expiry date. We were fined the other day because we "didnt" renew our report right after the visa got extended.

Apparently they tie-in the 90 day notif expiry on the day of your visa expiry.

you can mail it in as long as your packet is post marked 14 days or more before the due date (which should be on that tiny card they stapled into your passport like this
