What are the rules for extending an OA visa in Thailand, especially regarding health insurance coverage?

I forgot to mention that the

IS covered by one of the 14 thai approved insurance carriers. :)

While it is totally okay to get your O-A visa from your country using an insurance carrier there that meets the requirements, you cannot get any extension from an O-A inside the country without carrying the mandatory insurance requirements by one of the 14 thai approved insurance companies. The O/P is covered by Pacific Cross and they are one of the approved insurers for O-A visas ..

@Tod ********

can you please confirm you need to have made at least 1 extension on an A-O before you can get an extension based on marriage to a Thai? I was told I could do it at Hua Hin and given the list however we didn’t discuss about having made a previous (in country) extension? I also got in without having having insurance if that matters.

Now here's a thought, The O/P wants to switch (NOT to an O VISA) but to an extension based on marriage to a thai. BUT in order to do that from an O-A entry stamp they have to get at least one extension based on the reason they have the visa (retirement).

They could apply for the retirement extension this nov when their current year entry stamp runs out by meeting the financial requirements and showing their proof of insurance. BUT what would happen is, instead of them getting a year extension they would only get an extension good as long as their insurance policy is (Feb 2021).

Once they have that extension (no matter that it's less than a year) when it comes up to run out they could then apply for a NEW yearly extension based on marriage to a thai because they'd have followed the rule of applying for at least one extension for the reason they got the visa (retirement).

Okay, this is pretty much like I thought it was

They mis-typed that they are stamped in until Nov 2021 :/ they're stamped in until Nov 2020.

The O-A visa expired in Feb 2020 but they bounced out and back in back in Nov 2019 which gave them a new year entry stamp dated until Nov 2020.

They are insured until Feb 2021. SO that means IF they apply for an extension in Nov (and don't do anything with their insurance) they will only get an extension dated until Feb 2021 <- the date they are insured until.
