I guess we should define "long stay." I constantly hear bitching on the internet of people wanting to live here permanently, some retired, not really identifying as "tourists," maybe even has a bar or a dive shop, but trying to string along the government with back-to-back tourist visas. That day is quickly coming to an end. Interestingly, these are the ones who yell and complain the loudest.
I think I read that if you go back to your own country and get an annual retirement visa from the Thai embassy, you can show all your income (or 800K baht) in a bank or regular deposits stateside without having to deal with this Thailand-side documentation showing cash coming from outside the country. Anyone else hear of this?
