What are the requirements and considerations for obtaining a Digital Nomad Visa (DTV) in Thailand?

1a) As of now, no. But with the recent crackdown on ED visa holders for non-attendance I can definitely see that becoming a thing at some point.

1b) Yes. They aren't going to give you a 5 year visa for having a tooth pulled.

2) This visa is for Thai cultural pursuits and that is muay thai. You might be able to find a gym that teaches other things (BJJ, MMA, ETC) but I believe the basis must be MT.

3) For MT or cooking, you have to find a school that has been approved for DTV. Not sure about medical, but I imagine they will be more lenient with who is doing the treatment as long as they are a recognized doctor or facility. You should do a search in this group for medical posts.

4) I assume you mean getting the next 180 day stamp. Just do a border run. From people's shared experiences, in country extensions are a hassle and can be even harder to get sorted than when you first applied.

Nah most dont care if you dont attend your good

1) No

2) Muay Thai is specifically mentioned but there are other qualifying soft power options

3) Schools must be official government registered

4) In country extensions require ongoing courses, border bounces do not.
