Can I deposit money into my Thai bank account for a Non-Immigrant O visa extension upon arrival in Thailand, or must it be transferred from abroad?

Hi everyone,

Apologies if this is a silly question.

I have the visa information required to get my non imm 0 visa in UK , and also for making my first 1yr extension based on marriage ..( i was married in Nakhon Si Thammarat and will be living there and using local immigration office there for application.

First query is, i cant send money to my thai bank account from uk , but i can go into my kasikorn branch when i arrive and put the 400k in to season for the two months....

Will they accept funds for the extension doing it this way or does it have to be bank transfer from overseas bank ?

Secondly, i have a marriage certificate ( cor 3) and they also asks for a certicate of marriage registration ( cor 2 )

Is the cor 2 something i can get in Thailand or is there anything i need to do here for it?

Any help appreciated, im a worrier and just want to try get it all done correctly.

Thanks gang.
