Can I extend my stay in Thailand if I just got married on a tourist visa?

I came to Thailand on a tourist visa in 2020 to visit my girlfriend, got locked down for Covid for a year. Went back to Canada for 3 months, returned to Thailand April 2021 (got a 90 day visa tourist visa instead of using my ‘exempt’ privilege mistakenly believing a 90 day visa meant I could stay for 90 days instead of ‘use it within 90 days,) got married and converted to non-O marriage with no issue (other than the huge pile of paperwork as compared to a retirement non-O)

This was still during the ‘emergency powers’ period when immigration was not as strict as normal, so ‘your mileage may vary’ … significantly.

Get a good visa agent or lawyer would be my advice. A marriage visa is usually one of the more ‘complicated’ of the visa types to get … I used an agent and when I saw the stack of paperwork that I eventually had to sign (30 or 45 minutes of doing nothing but signing & initialing document after document!!) I was glad I did.

I came in on a tourist exempt and got married. They told me at Surin immigration to first do a normal 30 day extension (added after the expiration date). Then can get a 60 day extension for visiting family (starting from the day applied). After that there is no extension you have to get a non O visa. I went to savannakhet Laos embassy for the non O visa.

Do you have Thai children?

Sorry I was reading quickly while traveling to the airport but I'm sat down now. You should definitely be able to do the 60 day visiting Thai family extension.

You can’t use the 60 day married to a Thai extension unless you are here on a visa exempt stamp or on a non-o visa. You CAN NOT apply for it if you’re here in a tourist visa.

I don’t think u can do extension with tourist visa, you need get a non o first then after that do the extension

You must convert to the non-O visa first before you can apply for the 1 year extension.
