Can I obtain a work permit as a teacher on a Non-O visa and extend it based on that?

Just to add: The financial requirement is a minimum Thai salary of 40.000 thb a month, shown with the last 3 months of tax and sso payments from you and mentioned staff to get the work permit. Also werk permit copies are needed.

Immigration might ask for more company documents, so best is to pay them a visit before apply for the hand out.

make the copy, tick the box and when all done go back and it will go smoothly.

If you have a Non-O visa based on marriage to a thai OR raising half thai children, yes you can carry a work permit AND you can get a yearly extension (based on marriage or raising children) by using the income from your legal work here as proof of funds (meaning your salary is at least 40K baht a month)

No it's not the same paperwork for getting an extension based on employment because you aren't getting an extension based on employment 🙁

you'd be getting it based on marriage to a thai or raising thai children and you'd need the documents for that extension. The only thing your legal employment has to do is that you'd show your contract, pay stubs, tax deductions, salary history as proof of income.

I might be wrong but I believe they require a minimum of 3 months salary history to use legally working here with salary of 40K baht a month as proof of funds for the extension.
