On my entry visa is another university stated. I just changed my university now to UE, GISMA OR BSBI. How should we proceed in this case?

If the change of university takes place within the same city (Berlin) and relatively soon after your entry to Germany, then there is generally no reason to worry.

If the university was somewhere else entirely, the immigration office will have to check further.

We can still submit your case 8 weeks before the visa expiry date.

If you had a university change, please upload your old (from the other university) AND new matriculation letter under section 33.

How to upload: As the system allows to upload only one document, you can do a merged PDF to merge more documents as one and upload it under section 33.
