My Thai wife added me to her Bangkok Bank account a while ago. Over the years she’s made deposits inside Thailand as well as transferring money into the account from the USA. She’s got well in excess of several million baht.

Question: I’ve been told that when I apply for marriage visa that the money in the joint account must be 800,000 baht min (instead of 400,000 in my own account) cause it’s a joint account. BUT does it all have to be shown to have come from outside Thailand or does it matter since a it’s several million baht in the account? Thanks!
