Happened to me while I was home in Canada for a month - wet passport completely damaged
Got a new one using the expedited process
Visa/extension of stay/re entry permit all void.
Was able to get a new "sticker" for a new visa put into my passport from the Thai embassy (consulate?) in Toronto... Was able to sort it all out but a pretty expensive mistake!
, you won't ever need to do a "90" day report, because you "reset" everytime you re-enter.
You WILL need to register where you're staying, everytime you return. (first file from the hotel/SHA+ and then report once stationed in your residence.)
You will need most of the documents (proof of employment, gps/map location of your house (or the school/place of employment), various signed letters of proof from your employer) to be written in Thai (and some, such as your contract in both English and Thai) .....
Do you have all of the required paperwork already that you know of??
When you come back, they'll stamp a new "entry" date and also give you a new TM30 slip.
You will then need to report 90 days after the new date
HOWEVER... Your landlord or whoever you have as a Thai person that is responsible for you *should* report within the first 48 hrs of you getting home (not just arriving but actually back to your home address) as this needs to be done... But I'm pretty sure it's for your landlord or school to do.
be careful. "Reapply" for the Ed visa will not be the same as receiving an 'extension' of a current Ed visa
**correct me if I'm wrong
So, as mentioned ... Maybe talk to your school or even have someone on the phone from your school to speak with an immig. officer on Monday.
I feel like switching to the 'covid' extension and reapplying for an Ed visa might be a more expensive and time consuming process compared to just waiting for the extension and paying the overstay fees
