How can I obtain a Non-B visa for teaching while in Thailand with a 30-day stamp?

rather makes things easier for you than others. As I wrote above, people might have problems getting in-country Non-B after the Covid extension. But you have clearly another option currently.

@Валентина **********

, who told you that?

@Валентина **********

, you are on visa-waiver so you are not eligible for a 30days tourism extension. Your choice would be a Covid extension, an extension based on embassy request, or Non-B visa directly.

Have your new employer sort documents for your visa within 10days

or

have them talk with the local immigration office to check if that IO allows you to apply for in-country Non-B after Covid extension.

If no for both, you need to leave the country again.

sorry about that

wish you good luck

okay, same sense to Covid extension. Before, you could get in-country visas after Covid extensions. But it getting harder.
