Can I apply for a marriage visa in Thailand if I am currently on a tourist visa?

You can apply for it in Thailand. Make sure you ask it straight at the immigration desk for non O visa. I asked it in Changwattana (BKK), at the information desk they told me it can't be done in Thailand, so I went on to the non-O department where they told me "no problem". Most immigration officers are kind of confused about their own rules. Persistence, if you fulfill to all the requirements you will get it done.

Sorry miss read you there. You should be able to get another non o visa without going back to Finland

As far as I know As a UK 🇬🇧 citizen I got married in Thailand in the local registrars office in Khon Kaen. At the time I was just on a 30 day entry visa

I was today at Roi Et immigration. Because I am married with Thai having 2 kids with her I can extend my tourist visa after 26.9. two months paying 1900 bht. I think you don't need to go to Finland for marriage visa. You can get that visa from Thailand, but you must have 400.000bht in your bank account or monthly income minimum 40.000 to get marriage visa.

Are you over 50? I know you can get a retirement extension visa now, but it costs THB, 15 months and they put the 0THB in and out of your Thai bank account.

Okay, I think what the problem with people understanding what's going on was that you put that b/s about you having a Non-O visa BEFORE and then you went back to your country and it ran out

When you came back to thailand before the country closed you didn't enter on a Non-O visa OR on an extension but on a 30 day visa exempt entry or 60 day tourist visa which already expired putting you on amnesty AND there is NO immigration office that will sell you a 90 day Non-O visa based on marriage once you hit amnesty. You needed to have gotten after that task shortly after you got here back in March :( That's because you need "hard stamp" (real time) left on your 30 day visa exempt entry OR your 60 day tourist visa entry to apply for an in country Non-O visa because the application goes under consideration for a period of time before you go back and get it inked into your passport

I think you can cross the border , when it's open , and get type O visa. Then on return apply for the marriage visa after a couple of months. 400.000baht in Thai bank account.

Try buttercup visa they are in korat

Can you not apply for a 12 month extension of stay based on being married to a Thai national?
