What are the requirements for citizenship, and is dual citizenship now possible?

Length of residence: You generally need to have lived legally and habitually in Germany for at least 5 years. Citizenship after 3 years («Turbo-Einbürgerung») was abolished on 30 October 2025. If you have been married to a German citizen for at least 2 years, you can apply after 3 years of residence.

Other requirements: B1 German, the citizenship test (Einbürgerungstest) or an equivalent certificate, the ability to support yourself and your family without state benefits (Grundsicherung or Sozialhilfe), a declaration of commitment to the constitutional order, and no serious criminal record. Your type of residence permit must also qualify; some temporary permits do not count.

Exception for state benefits: If you have worked full-time for at least 20 of the last 24 months, or you are married with children and your spouse works full-time, receiving temporary benefits may not always be an obstacle. Ask the naturalisation office about your situation.

Dual citizenship: Since 27 June 2024 you no longer have to give up your previous citizenship when you become German. You can keep your Turkish citizenship. Contact the consulate to update your records on the Turkish side.

Applying: In Berlin you apply for citizenship online at the State Office for Immigration (LEA). Because there are many applications, processing can take a long time. The fee is 255 euros for adults and less for children applying together with their parents; check the current fee.
