维也纳大学的网站上面说For the respective documents you need the legalisations from the Ministry of Education and Ministry of Foreign Aff airs of the issuing country. With these legalisations you turn to the Austrian embassy or consulate in the issuing country. It is most important to get all three legalisations on all documents.
