Just looking for confirmation ...........
I just did my 90 day report online and had it approved. The next due date is now 31 May. I leave Thailand for a holiday back home to the UK on 21 May, returning 5 June, so my next 90 day due date is while I am away.
When I return I will go file a new TM30 with my new TM6 landing card. I will also be returning on a new passport.
I assume they will then give me a new date for 90 days, and that no fines will be involved, and they will transfer my non imm O extension of stay into my new passport?
Thanks
TLDR : Answer Summary
The user confirmed their 90-day report was approved, but they seek clarification about the due date coinciding with their travel. Commenters clarified that the next 90-day reporting date is based on the number of days spent in Thailand and suggested that the user will have to report in person upon return.
