What give away? If I move to Vietnam, by choice, or because I refused to jump through Thailand's hoops, my visa runs would be dual purpose. I would time the 3 months to take in a sporting event, festival, concert, Pattaya catch up, whatever. I have said this before. I go to the Singapore F1 every year anyway, so there's one visa run straight away. Like another member says, I can actually do 6 months in Thailand and 6 months in Vietnam, if I want, and not be a tax resident of Thailand, and not have to jump through any hoops here. Vietnam is my Plan B. Thailand can crackdown all they like, make it as hard for foreigners all they like. They can kick me out if they like. I couldn't care less.
