German Citizenship in 2026: Timelines, Requirements and Application Details

Germany’s naturalisation rules changed following the citizenship reform, but one key detail for 2026 is this: the standard minimum period of residence is five years, and the previous option to apply after just three years based on special integration achievements was abolished on 30 October 2025. At the same time, multiple citizenship is generally permitted in Germany, so giving up a previous passport is no longer a standard requirement for naturalisation.

What has changed compared with the 2024 rules

In 2024, Germany reduced the standard residence period for naturalisation from eight to five years and permitted multiple citizenship more broadly than before. For a short time, the law also provided for expedited naturalisation after three years for special integration achievements.

For applications in 2026, this section must now be understood differently: the three-year rule is no longer in force. The official position of the Bundesregierung is that citizenship is possible no earlier than after five years of residence, provided the other requirements are met.

Basic requirements for Einbürgerung

According to BAMF, entitlement to naturalisation generally arises when several requirements are met:

• five years of ordinary and lawful residence in Germany;
• verified identity and citizenship;
• a suitable residence permit at the time of application or naturalisation;
• commitment to Germany’s free democratic basic order and to additional obligations linked to Germany’s historical responsibility;
• the ability to support yourself and your family members without Bürgergeld or Sozialhilfe under SGB II or SGB XII;
• no significant criminal convictions;
• German language skills at least at B1 level;
• knowledge of Germany’s legal and social order, usually demonstrated through the Einbürgerungstest or a recognised equivalent.

Exceptions or concessions may be possible in individual cases, but they are assessed by the Einbürgerungsbehörde. It is therefore best to discuss borderline situations with the authority at your place of registration in advance.

Multiple citizenship

Following the reform, giving up previous citizenship is no longer a general rule for naturalisation in Germany. But that does not mean a second passport is always retained automatically: you must separately check the laws of your current country of citizenship. Some countries restrict dual or multiple citizenship regardless of German rules.

How the residence period is calculated

Federal sources formulate the basic criterion as five years of ordinary and lawful residence in Germany. Practical questions — for example, how studies, interruptions, changes of status, long absences or earlier residence periods are counted — may depend on the details of the case and the administrative practice of the particular federal state.

If you have had a student residence permit, moved to another federal state, had interruptions in registration or have an unclear residence history, it is safer to request a written assessment from the Einbürgerungsbehörde or seek specialist advice before applying.

Documents and regional differences

The application process differs from city to city. In some places applications are submitted online, while elsewhere they are made using a paper form or in person. Document lists also vary, so you should check the basic set with the authority at your place of registration.

Usually, the following are prepared in advance:

• a passport and documents proving identity;
• a valid Aufenthaltstitel;
• a Meldebescheinigung or registration history, if required by the city;
• proof of income and employment;
• a tenancy agreement or proof of housing, if included in the local list;
• a German-language certificate;
• the result of the Einbürgerungstest or a document that replaces the test;
• documents on marital status and children, where applicable;
• additional proof of stable income for self-employed people, freelancers and entrepreneurs.

It is better not to rely only on a random list from the internet. If the city publishes its own checklist, it takes priority over a general description.

Einbürgerungstest

The Einbürgerungstest consists of 33 questions and allows 60 minutes. To pass, you need to answer at least 17 questions correctly. Three questions relate to the federal state where the applicant is registered with their main residence.

The test can usually be taken at authorised Prüfstellen, including a Volkshochschule. If there are few available dates, it makes sense to ask the authority whether it will accept a test result obtained elsewhere and how to choose the correct federal state for the state-specific questions.

Students, freelancers and entrepreneurs

For students, the main risk is not studying itself, but how the authority assesses the lawfulness and continuity of residence, future status and ability to support oneself. Because practice may differ, disputed study periods are best documented.

Freelancers and entrepreneurs generally need to demonstrate stable income convincingly. Simple bank statements may not be enough: the authority may request tax documents, a Steuerbescheid, an Einnahmenüberschussrechnung, BWA, contracts, invoices or other evidence of regular income. The exact set depends on the city and the type of activity.

What can delay processing

• An incomplete set of documents or documents without a translation where one is required.
• An unclear history of residence, registration or absences from Germany.
• Income that is difficult to prove with official documents.
• Different spellings of a name, date of birth or citizenship across documents.
• Waiting for the result of the Einbürgerungstest or language exam.
• Applying under outdated rules, for example by relying on the abolished three-year rule.

Conclusion

For 2026, the main practical framework is this: naturalisation in Germany is generally possible after five years of lawful residence if the requirements concerning identity, residence permit, income, language, the test and commitment to the constitutional order are met. The expedited three-year naturalisation rule is no longer in force, while multiple citizenship is generally permitted in Germany. Before applying, check the local document list and any disputed residence periods with your own Einbürgerungsbehörde.
