What are the requirements and steps to apply for a Non-OA visa in Thailand, and can I do it without an agent?

Can I get the current requirement for health insurance between a NON-O and a NON-OA.

I recently documented, on my Travel Blog, the process as it applies in the United Arab Emirates. You may find some useful tips there as the process should be similar around the world. Good Luck 🇹🇭🙏🏻

To answer your question about 90 day report, it only applies to those on long term extensions and only if you stay in country 90 days or longer without leaving. DTV may be different as its 180 day stays but I don't know.

You can’t apply for a Non O-A in Thailand. Only a 90 days Non O visa and apply for a one year extension of stay.

As you seem to be from the US your embassy in Bangkok doesn’t offer to give you a affidavit letter regarding income, so you’ll need to prove 800K baht in your account in Thailand as an international transfer to apply. For the second year you can switch to the income method by showing proof of twelve months consecutive transfers of minimum 65K baht a month.

You’ll need 14-21 days left on your stamp to apply but your biggest issue will be to opening a bank account in Thailand on a short stay. If you apply for the 90 days Non O visa at home before you leave with your income or funds, you’re making everything more easy for yourself.

Regarding opening bank accounts most bank requires minimum a Non O visa, some also your first year extension of stay.

You cannot get a non-OA visa in Thailand. This visa is only available from the Thai embassy in your home country.

You can get a 90-day non-O visa in Thailand, but that's not a good idea. You won't be able to open a bank account as a tourist and having the required funds in a Thai bank account is one of the requirements if you try to apply for the visa in Thailand.

You should do it the way it's meant to be done, by applying for the non-O visa from a Thai embassy, which let's you show the required proof of funds from anywhere. Then when you get to Thailand you can use your non-O visa to open a bank account and transfer the money you'll need to apply for your 1-year extension.

Unless your embassy in Thailand offers income verification (many do not) then you won't be able to use monthly income for your extension. The only thing immigration will accept for the first year is 800,000 in a Thai bank account or embassy verified income.

You can only get a Non-OA from your country of residence, check the Embassy website
