2026 Dual Citizenship Guide: How Turks Can Become German Citizens

Germany introduced important changes to its citizenship law, allowing more people to apply for dual citizenship. This reform has created new opportunities for many Turkish residents who have been living in Germany for years.

Under the updated rules, applicants may be able to keep their Turkish citizenship while becoming German citizens, provided they meet certain requirements such as residency, language skills and financial stability.

Applicants typically need to provide several official documents when applying for German citizenship:

• Valid passport and identity documents
• Proof of long-term residence in Germany
• German language certificate (usually level B1)
• Citizenship test certificate (Einbürgerungstest)
• Proof of income and clean criminal record

With the recent law changes, the required residency period may be reduced in some cases. Applicants who show strong integration into German society may qualify earlier.

Experts recommend carefully preparing documents and following official updates from German immigration authorities before starting the application process.
