Good to know
The essentials for applications at the immigration office.
Renewing a residence permit
If you apply before your permit expires, it continues to apply until the office decides (§ 81 (4) AufenthG).
Guide (in German)Fiktionsbescheinigung
The office issues a certificate on the effect of your application (§ 81 (5) AufenthG). Whether you may work with it depends on the application.
Guide (in German)Settlement permit
Niederlassungserlaubnis: as a rule after five years with a residence permit, for skilled workers after three years (§ 9, § 18c AufenthG).
Guide (in German)Naturalisation
A claim after five years of lawful residence (§ 10 StAG). The citizenship authority is responsible; in many places that is not the immigration office.
Guide (in German)Moving
Register your new address within two weeks (§ 17 BMG). Which office is responsible afterwards is a matter of state law.
Guide (in German)Formal obligation
Verpflichtungserklärung: whoever invites someone is liable for five years for public funds spent on that person’s living costs (§ 68 AufenthG).
Guide (in German)No decision
After three months without a decision you can usually bring an action for failure to act (§ 75 VwGO).
Guide (in German)Rejection
One month for an objection or a court action; neither suspends the rejection (§§ 70, 74 VwGO, § 84 AufenthG). An urgent application to the court can.

How do I get an appointment at the Ausländerbehörde Ilm-Kreis?
The office gives appointments online on its own website: https://termine-reservieren.de/termine/ilmkreis
Which places does the Ausländerbehörde Ilm-Kreis serve?
16 towns and municipalities, among them Ilmenau, Arnstadt, Geratal, Stadtilm, Amt Wachsenburg, Großbreitenbach, Plaue, Elgersburg 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.
