Frequently asked questions

How do I contact the Ausländerbehörde Köln?

Address: Dillenburger Straße 56–66, 51105 Köln. Phone: +49 221 221-0. Opening hours as published by the office: Persönliche Besuche und Vorsprachen nur mit Termin und Einladungsschreiben; Termine schriftlich per E-Mail, Kontaktformular oder Post.

How do I get an appointment at the Ausländerbehörde Köln?

The office gives appointments online on its own website: https://www.stadt-koeln.de/service/onlinedienste/kontakt-auslaenderamt/index.html

My residence permit expires and I have no appointment yet. What applies?

The application counts, not the appointment: if you apply for the extension before the permit expires, it is deemed to continue until the office decides (§ 81 (4) AufenthG). Apply in a way you can prove, for example in writing or through the office’s online form.

Is the immigration office also responsible for naturalisation?

Not everywhere. The naturalisation certificate is issued by the citizenship authority (§ 16 StAG); which body that is locally is decided by the federal state. In many places it is a different office.
