After your arrival and as soon as you receive your rental contract, you need to register as a new citizen of Weimar at the immigration office ("Ausländerbehörde Weimar"). 

In order to arrange an appointment, please write an E-Mail: auslaenderbehoerde[at]stadtweimar.de

Upon the appointment, you will have to show your rental contract as well as the so-called 'Wohnungsgeberbestätigung' filled in by the landlord.

The confirmation of registration will be important for the application for your residence permit (Aufenthaltstitel) and to open a bank account. 

If you are not a citizen of the EU, of an EEA country or Switzerland, you need to change your visa into a residence permit (Aufenthaltstitel). Please make sure to first register your address in Weimar.

For this, you need to apply for a residence permit for educational purposes at the immigration office before your visa expires. Please start the process online (or submit all your documents as hard copies via postal mail): Aufenthaltserlaubnis zum Zweck der Ausbildung

As the residence permit is valid for only a limited period of time you might have to prolong it during your stay. Please contact the International Office regarding the required stamp on your enrolment certificate.
