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.

@Mike *******

Just imagine the chaos at the airports, if immigration at the borders would be closed and even if it's just for two hours.

Only if arriving by air. By land you still have to fill out the TM6.

1. Report to police as lost or stolen

2. Take police report and any other means of identification to your Embassy

3. Take Emergency Documents and letter from the Embassy (and if possible, your Embarcation Card) to Immigration to get a new "Permission to Stay" stamp in your Emergency Passport.
