Once you are admitted to the MSCE program, you can download an official Letter of Admission ("Zulassungsbescheid") in your TUMonline account. You should apply for a student visa immediately after receiving the official letter of admission and apply for a room.
Prepare for Munich!
Now it's time to prepare for Munich! We expect you to arrive in the first two weeks of October. This will give you enough time to familiarize yourself with the university, complete enrollment procedures, and meet other students and community members. You may take an intensive language course or prepare yourself for the MSCE program.
Until then, there are still a lot of things to do: Applying for a student visa, applying for student housing, arranging health insurance, etc.
