Anonymous participant it's good for 180 days at a time, over 5 years. At 180 days, you have to extend or go out of the country and come back in for a fresh 180.
As it stands now, if you extend in country, you basically have to meet the same requirements as your original application.
Leaving Thailand and coming back doesn't have the same level of scrutiny at this point.
if you're from the US, and you're doing a non O, you'll still have to deposit 800k for the first year in a Thai bank. In that first year, deposit 65k every month. In the 2nd year, you can do the income method.
There are some details, but that's the big picture.
I just read up on it. There are several visa types that require insurance. And there are many situations that do not legally require health insurance if going to Thailand. If you can point to a law that says different, I'm happy to correct myself.
You are not required to have health insurance to live in Thailand. The non-O doesn't require insurance on renewal. The non-oa has an insurance requirement, and perhaps others, I'm not sure.
I would guess it's a mistake. They copied the text over from the OA visa email or something. Remember immigration isn't that familiar with renewals of this visa yet.
If you're coming to Thailand, get used to things not making sense. And get used to different offices of the same branch of government 'interpreting' laws and regulations differently.
it's my understanding that Thai taxes are based on money remitted to Thailand only, and not worldwide income, but they are considering adding the worldwide income aspect.
