Can I use a UAS admission for my German visa and later switch to a public university via deferred admission?

You can legally apply for your German visa using an admission letter from a university of applied sciences and later move to a public university once your deferred offer opens. The key risk is timing, since even a short gap without active enrollment can invalidate your residence status.

The Safer Dual Enrollment Route

Rules That Protect Your Status

• Never de-register from the UAS until you hold written proof of enrollment elsewhere.
• Within your first 18 months, you can switch once without prior approval if the new field is similar.
• Switching to a completely different field invites a stricter review.
• Update your Ausländerbehörde and address registration promptly if you change cities.

My Advice

Keep both admission letters and your enrollment proof from the UAS in one folder before you attempt the switch, and book your Ausländerbehörde appointment the same week you enroll at the public university so your residence permit paperwork stays current without any lapse.
