How do I get an appointment at the Ausländerbehörde Rhein-Sieg-Kreis?

Which places does the Ausländerbehörde Rhein-Sieg-Kreis serve?

18 towns and municipalities, among them Sankt Augustin, Bornheim, Hennef (Sieg), Siegburg, Königswinter, Niederkassel, Lohmar, Rheinbach and others.

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.
