Take a quick trip to South Dakota and change your address to there. They have services all set for just that. Register to vote and drivers license. Easy I have a buddy that did it. Wish I had!
One of the other things to think about is city or country . I’m 100k out of Chiang Mai and almost everything is less expensive here. Personally I enjoy the laid back pace here.
There are some great gals out there. You just need to take care. Understand too the culture is very different. That said I got lucky you can too. All the best!
