I've booked a flight out of Thailand for the day before I'm supposed to do my 90 day reporting visit to the local immigration office.

I was wondering if I still need to do the 90 day report because I'll essentially be telling immigration at Suvarnabhumi where I'm living on the departure card.

BTW, I've already got my re-entry permit.

Thanks.

just go out you have 7 days before or after, remember upon return the day of return is day 1 of the new 90 days

Since it is the day before you are suppost to do your report, you are not staying for 90 days and do not have to report.

You next report is 90 days from the day you re-enter Thailand.

The window is only if you report in person and is 15 days before until 7 days after - if you fail to report there is no window. But for this poster he is leaving before the report is due so no problem.

Thanks very much for the informed replies.
