What are the current rules regarding changing from student or volunteer visas to work visas in Thailand?

@Gwen *********

the REAL question IS

How did you get the year extension you have based on volunteering that you have now?

IF you handed your passport and a pile of baht to someone who took it to a province you don't live in, used an immigration office you don't go to, got you a Non-O and then a year extension for a foundation you can't pronounce let alone ever volunteered at, you WILL have problems trying to get off it :(

Now,. on the other hand IF you got documents from your foundation, went to the immigration office where you live, applied for the Non-O visa and then the year extension you shouldn't have ANY problem following my first comment, cancel your current extension, get a covid extension and then apply for an in country Non-B visa with documents from your new employer.

BUT

Back to the question I asked: did you get the volunteer visa on your own at the immigration office OR did you get it by "alternate means" <- that's gonna be the linchpin as far as whether you can or can't do anything

If you leave Thailand, you need to cancel your current extension clearly before your departure. The procedure to leave the country hasn't changed..

You would need to cancel your current extension of stay, get on another type of extension (covid for example) THEN you could apply for an in country Non-B visa. You can't go from an ED visa extension to one based on employment. You MIGHT be able to do it from a volunteer visa extension but that's between you, your employer, the immigration office and the foundation you volunteer for now.

Post on a C/M related f/b page and ask you question.
