. . . as an Austrian citizen, you can get a multi entry Tourist Visa only in the country where you have your registered residence. Or in the home country of your citizenship. You CANNOT get a multi entry Tourist Visa in ANY of Thailands neighbor countries. . . . . . . . . all you can get issued in Thailand's neighbor countries is a "Single Entry 60-days Tourist Visa". On most of the Thai embassies and consulates, you will need to make an appointment first. The only walk-in Thai embassy is the consulate in Savannakhet and Ho Chi Minh City
