visa

Austria is member of the European Union and the Schengen Agreement. Therefore, for most of the citizens of European countries a photo-id is sufficient to enter Austria. For many other citizens around the world a valid passport is sufficient. All other citizens need a Schengen visa to enter Austria. Please check the following link of the Austrian Embassy in London if you will need a visa to come to Graz. For all participants who will need a visa we will provide letters of invitation shortly after the registration.
