Can I extend my family O visa in Thailand if my Thai daughter turns 20 during my stay?

ORIGINAL POSTER
Looking for some advice. I am from the UK, and presently in the UK. I am a mother of a 19 year old daughter, who has thai citizenship. I contacted the London Embassy and they said that I can apply for a family 0 visa, to spend time with my daughter, while she looks at universities in Thailand. However, my daughter turns 20 in March, and so my question is, does this mean that my visa at the end of the 90 days, will not get extended, as my daughter will then be 20? (as I am to understand, 19 years is the limit on visa for a parent) I want to stay 1 year in Thailand with her, but concerned if they will continue to extend the 0 visa due to my daughter's age.

TLDR : Answer Summary
The family O visa allows a parent of a Thai citizen to stay in Thailand, but this visa can only be extended while the child is under 20. Since the individual’s daughter will turn 20 during her visit, the visa is unlikely to be extendable beyond the initial 90 days. Alternative options include applying for a retirement visa if eligible or exploring other visa types.

Why not think a bit long term and consider a DTV supported course?

And on the chance you're not over 50 and wouldn't qualify for the retirement visa/extension you would have to find an alternate way to stay should you decide to stay here a year.

There's no problem getting the nano based on having a Thai child coming in and getting the 90 days and staying the full 90 days that Visa allows, you just couldn't extend it

You are correct, you cannot use support of a Thai child as a reason to stay in Thailand once the child hits 20 years old.

If you're over 50 you could apply for a non o based on retirement, get here get 800k in a Thai bank account and get a year extension that way.

you definitely would need to find another way to stay as raising Thai child is not going to be a viable option given the age of your child.
