German citizenship (Einbürgerung)
Naturalisation is the goal for many long-term residents, and the process is long and document-heavy. This guide explains the requirements, roughly how long it takes, and what the waiting and document requests look like. Some details depend on your Bundesland, so always confirm them with your local office.
Who can apply for German citizenship?
In general you need five years of lawful residence, a settled status, enough German (usually B1), a passed citizenship test, the ability to support yourself, and no serious criminal record.
Five years of lawful residence is the minimum for everyone. Exact requirements can depend on your Bundesland, so confirm with your local office.
Do I need permanent residency first?
Not always. Citizenship counts your years of lawful residence, and many people apply from a temporary residence permit once they meet the requirements, without first getting permanent residence (Niederlassungserlaubnis).
Permanent residence is a separate status with its own, usually shorter, timeline. Some people pursue it first, but it is not always required for citizenship.
Can I keep my old citizenship (dual citizenship)?
Yes, in most cases. Germany allows dual citizenship, so you can generally keep your original nationality when you naturalise.
Your home country's rules also matter, because some countries restrict holding two passports. Check both sides before you apply.
How long does it take?
It varies widely by city, from several months to well over a year, and long waits with several document requests are common. Some offices acknowledge applications slowly.
Applying with a complete file helps, and you can follow up in writing if you hear nothing for a long time.
What documents will they ask for?
Expect identity and residence documents, proof of income and pension contributions, your language and test certificates, tax and rental records, and civil-status certificates.
Offices often ask for more during the process, so keep everything organised and be ready to send updates.
They asked for proof of rent or income I cannot show right now. What do I do?
Explain your situation in writing and provide the closest evidence you have, such as a tenancy contract, bank statements, or a letter from your employer.
Gaps do not automatically end an application, but silence can stall it. Answer every request by its date, even if only to say what is coming.
Does time abroad or a missed Abmeldung affect my application?
Long absences can interrupt the continuous-residence requirement, and an unclear registration history can complicate things.
If you were stuck abroad or did not deregister, gather proof of your actual living situation and dates, and explain it clearly rather than hoping it is not noticed.
What happens after I am approved?
You are invited to receive your naturalisation certificate (Einbürgerungsurkunde). After that you can apply for a German passport and ID card.
Keep the certificate safe, because it is the proof of your new status.
