IMMIGRANT O FAMILY EXTENSION 60 DAYS?

hi I have a immigrant O 90 day visa based on having a child in Thailand I'm not married

My 90 days is almost done,I want to stay in Thailand another 60 days I was planning on getting the covid 19 extension but that is no longer possible

Can I extend my visa for another 60 days? based on family reasons,I have seen some information that's it possible but nothing conclusive its very difficult to find information about this

I know this visa can be extended for 1 year regarding having 400,000 in a thai bank,I do not have this amount in my bank account and was hoping the 60 days extension if possible would have different requirements to 1 year extension

Any advice would be appreciated

Hi everyone, Merry Christmas.

This question has probably already been asked, but I would like to double check with you guys: this time I came to Thailand with a 30 days visa exemption stamp and got a 60 days extension at the immigration; would I be able to obtain a work permit considering these conditions?

Note: I'm not sure this makes any difference or it could help me make the next move, but I am here for family reasons, visiting my wife's family.

TIA for your time and replies,

Have a great Sunday.
