Colin Boyland correct. The funds can come into your account from anywhere for marriage visa. Do not have to come from overseas. They just want to see 400k baht in your account seasoned for the 2 months prior to the day ‘you apply’.
I’ll leave the ‘documents’ queerie to Tod and Ellie as it can vary from different offices.
speaking from my experiences Colin all of what you said is spot on (for myself and wife anyway). And the funds don’t need ‘international’ flagging. But not sure about the mention of ‘using last years documents’ ?
But there is a lot more paperwork and running around with the marriage visa as opposed to the retirement visa.
