The Learning Agreement is a contract between you, your home university and the hosting faculty at Bauhaus-Universität Weimar. You can find all of the important information here.
Students from non-EU countries require an entry visa. Please note: a tourist visa CANNOT be converted to a student visa. You will find more information on visas and rules on the DAAD pages.
In Germany all students must have health insurance. You can find out what this means for you and which documents you have to submit during enrolment here.
You can live in a hall of residence, shared flat or private flat. Finding something is not very easy. You should start looking as soon as you know you are coming to Weimar.
Weimar is very easy to get to. Being in the middle of Germany is beneficial. Back in the day it took Goethe two full days to travel from Frankfurt am Main to Weimar but now it takes just under two hours.
