Those who plan to live in Germany or wish to obtain German citizenship often ask questions such as how to become a German citizen and what the application requirements are. Below is a clear guide to the main points and procedures.
How to Apply for German Citizenship
Applicants should be aware of several important steps and required documents. Key information for the German citizenship application is listed below:
- The applicant must go in person to the relevant Citizenship Office (Einbürgerungsbehörde) in their place of residence.
- From the Citizenship Office, applicants must obtain and complete the “Antrag auf Einbürgerung” application form in person.
- Applicants aged 16 or older must submit the application themselves.
- For applicants under 16, the application must be submitted by a parent or legal guardian.
- A birth certificate is required.
- Employed applicants must provide payslips and copies for the last three months.
- If unemployed, applicants must provide documentation of unemployment benefits and copies.
- A passport issued within the last 10 years is required; at least two blank pages must be available.
- A marriage certificate and a copy must be provided if applicable.
- If divorced, a certified court decision and its German translation must be provided.
- Proof of German language proficiency, such as a diploma or school certificate, is required.
- If the applicant has children, school reports for the children should be submitted.
Citizenship Assurance Certificate (Bescheinigung über die Einbürgerungsvoraussetzungen):
This certificate is issued by German authorities to confirm that an applicant meets language proficiency and other requirements for naturalization. The certificate is usually valid for two years and may be extended when necessary.
Certificate of Release from Turkish Citizenship:
If applicable, the original Turkish-language document indicating release from Turkish citizenship, together with identity card and passport, must be submitted. Translations may be required.
Certificate of Naturalization in Germany:
A German translation of the release from the previous citizenship should be included when requested.
After verification of the documents, the applicant must personally sign a declaration affirming loyalty to the German constitution. Certificates proving sufficient German language skills must also be provided.
If no language certificate is presented, the Citizenship Office may require the applicant to take a language test.
An official at the Citizenship Office may ask questions in German and assess the applicant’s ability to understand a daily newspaper text. If language skills are not deemed sufficient, the application may be deferred until the applicant reaches the required level.
If the applicant’s German is found sufficient, naturalization procedures are typically completed within 10–12 weeks. Once approved, a Citizenship Assurance Certificate is issued, usually valid for two years.
What Are the Requirements to Apply for German Citizenship?
There are several criteria for applying for German citizenship. These requirements vary depending on the applicant’s circumstances. The main rules are as follows:
By descent (jus sanguinis):
- A person with at least one German parent is generally considered a German citizen by descent. Since 1 January 2000, if a child is born in Germany, the parent must have lived in Germany for at least eight years or hold a permanent residence permit for at least three years for the child to automatically acquire German citizenship.
By birth in Germany (jus soli):
- If a child is born in Germany to parents who are citizens of another country, certain rules apply under German nationality law. Between ages 18 and 23, such individuals must decide whether to retain German citizenship or the foreign citizenship; failure to declare a choice by age 23 may result in loss of German citizenship.
Under immigration law:
- Under the Nationality Reform Act, a general requirement for naturalization is lawful residence in Germany for eight years. Applicants must have a residence permit or settlement permit, sufficient German language skills, and no serious criminal record.
Other common requirements include:
- Signing a declaration of loyalty to the German constitution.
- Demonstrating German language ability in writing and speaking according to the Common European Framework of Reference for Languages.
- Having lived in Germany for eight years (reduced periods may apply in specific cases, such as completion of integration courses).
- Basic knowledge of German social and legal order.

- Renunciation of previous citizenship(s) is generally required, although exceptions exist.
Anyone over 16 who meets these conditions may apply for German citizenship.
