Best visa option.
I'm moving to Bangkok in four to six weeks to be with my Girlfriend. We're getting married this year and I've always wanted to move there anyway. Im 57 this year with enough money to be ok for a few years. If I get a non immigrant O visa, I can open a bank account, but if I do an advanced Thai cooking course (which I'm considering anyway), then I can get the 5 year DTV visa. Both seem good options but I can't pick a clear winner. I'll also change to a Marriage visa later too and I'm not sure which visa type will make THAT easier or even possible inside Thailand. Thoughts?
