Hello

We need help with the Non Immigrant O Marriage Visa, since we keep running into different information and can't find a legit source.

I am thai citizen and my fiance (U.S citizen) is already here in thailand with the tourist visa. We are going to register our marriage next month. After that, we want to apply for the Visa.

Confusing to us:

1. some sources claim that we need

- proof of income

AND

- X amount of THB on an account

some sources say we only need one of these requirements. What is true?

2. How do we prove the income? Does it has to be a bank statement with his name or can it be the bank statement of my name (the income gets transfered to my account, because he can't open an account without visa).

Would it even be possible to prove it with a letter from his employer?

3. We are not sure if/how we are able to apply with him being here already. On the website it seems we can only apply from abroad.

We would appreciate any kind of help and support! Thank you!
