1. I'm going to apply for translation or language (it seems that I only apply for German language and literature). Personally, I think the translation major of Innsbruck University is the best, but it is remote and far from Vienna in all aspects. Which one should I choose?

You should choose the University of Vienna. Both undergraduate (6 semesters) and graduate (4 semesters) have German majors, and there is no tuition (only a student membership fee of 17.50 euros is required). Housing has a single dormitory (220-290 euros)

2. Does the third foreign language (except English, German and Chinese) required by the translation major have to reach a high level before entering the major or after entering the major?

It is best to have a foundation, but it is generally available when entering school;

3. Can anyone introduce the dorms of Innsbruck University and Vienna University? do you have a single room? Yes!

Innsbruck University is very remote. Although it is close to Munich, Germany (about 150 km), it is far from Vienna (530 km). In Vienna, you can go to a concert on New Year's Day.

Good luck!
