Hello to you!
As you might have noticed most of this page is in german. This will be most likely the status quo and won't change. Nontheless you might want specific information or general help.
First of all we want to point to the universities International Student Services and Global Office. As the experts they are more likely able to help you with more general questions about being an international student. Most questions about applications, visa and being abroad, that we as student representatives don't have experience with, can be answered by them. At he Global office site you will also find support services and programms for incoming guest students at Goethe-University.
