Residence permits are issued for limited periods — students typically get 1–2 years at a time, workers the length of their contract. Extension is routine, but only if you start early.

The golden timeline: contact your Ausländerbehörde 8–10 weeks before expiry. As long as you apply (or provably try to) before the expiry date, your stay remains legal even if the appointment lands after it — you'll get a Fiktionsbescheinigung if needed for travel or work.

Standard extension documents:

Passport + current eAT card
Biometric photo
Proof of financing (blocked account/scholarship/payslips — students; contract + payslips — workers)
Health insurance confirmation
Students: current enrolment certificate and often a transcript / study progress confirmation — the office checks you're progressing within the allowed total study duration
Current Anmeldebestätigung if you moved

How you apply is wildly city-specific — some cities have online portals, some want an email first and then decide internally how to proceed, some book you straight in. This is exactly where city-specific knowledge saves weeks: select your city above.

Changing status? Finishing studies → job-seeker permit (18 months) → work permit / Blue Card conversions all happen at the same office with similar timing rules.

Red flags:

Applying after expiry. You lose the automatic legal-stay protection — the single most damaging unforced error in this whole journey. Set a reminder at the 10-week mark the day you receive any permit.
Study-progress problems surfacing silently: repeated semesters with few credits, or switching degree programmes without telling the office, can turn a routine extension into an interrogation. Change course early and openly, not silently.
Stale financing proof — last year's blocked-account statement or payslips from a job you left don't count.
A lapsed health insurance (unpaid premiums) showing up in the file at exactly the wrong moment.
Travel booked during the processing window without confirming your Fiktionsbescheinigung covers re-entry.
