Simple answer is no. As you are American the only way to officially qualify for a retirement visa inside Thailand is by putting 800k in a Thai bank.

@Bim *******

that's not really relevant as it's your fiance that needs the visa not you.

@Ellie ******

I understood that but wanted to clarify for the original poster

Only if you are on an extension of stay rather than a visa (check your passport) and then only when you go to apply for your next extension of stay. You just apply under the new reason ensuring you meet all the criteria

@Carl *******

it's allowed but after one or two times you will likely be question by immigration and possibly denied entry

You could probably get the initial 90 day Non-O visa in your home country before travelling to Thailand based on your monthly income but you will still need to put 800k in a Thai bank for your first extension. During this time you transfer a minimum of 65k baht each and every month for a full 12 months prior to applying for your 2nd extension you can use that

So what's your question?

It does seem a particularly short course. Did they indicate what length of course would be required?

@Ellie ******

q2. An overseas employment won't be accepted and he can't be working in Thailand as he's on a tourist visa

@Ručman **********

he can't hold a work permit without a visa that allows him to do so
