After 3 days in Chiang Rai finally I knew that my foreigners could not do Thai Visa here (at border of Myanmar) and they got only 15 days extension tourist Visa. So we had to go to Northeast Nong Khai province then let them across Thailand border to Laos to do Thai Visa at Thai Embassy over there. So all foreigner if you want to stay in Thailand more than 1 month you must do Thai Visa at Thai Embassy in your country before come to my country. Otherwise you have to go across the border until you get tired and wanna go back home.
