I am doing the same thing, but with the e visa online in my country, so there is no desk to ask. In order to apply for it for my wife, as a spouse , do I have to get it first? or can I apply for them together as far as you know?
Here in Mae Hong Son you can get a residence certificate even with a tourist visa (I have registered scooters and you can also get a driving license), but I don't think it's enough to open a bank account.
