Can I extend my NON-IM visa for study in Thailand and what are the reporting requirements?

Welcome to the party 🎉

once you do your 14 day quarantine, get ahold of your school and start them getting the documentation together so you can apply for your 90 day extension when your 90 day stamp runs down. You will need to file a TM30 once out of quarantine BUT you won't do any 90 day reporting until after you get that first extension. They'll put a paper in your passport telling you when your first 90 day report is due.
