exactly this. I did my 90 day notice yesterday (rural immigration office) and we asked about process of transitioning to Non-O under marriage. The immigration officer gave us a full list of requirements (in Thai) but emphasized that I would need to open a Thai bank account and place 400k into the account for 2 months. The IO was adamant that I could open a bank account with a DTV, but I didn’t want to argue or embarrass her, so we just accepted what she said and left. The other option she said that if me and my spouse had a joint account, we would need 2x the amount, but not sure if that fixes the issue, if one can place their name on a spouse’s account.
