German Citizenship Law Reform 2024-2025: The Nationality Modernisation Act Explained

German citizenship law underwent its most significant transformation in January 2024 when the Bundestag approved the Act to Modernise Nationality Law (Staatsangehörigkeitsmodernisierungsgesetz, or StARModG). Signed by President Steinmeier on March 22, 2024 and published in the Federal Law Gazette on March 26, the law entered into force on June 27, 2024. A subsequent amendment in October 2025 removed the accelerated three-year naturalization pathway, establishing five years as the universal minimum.

This article provides a comprehensive regulatory analysis of the current German citizenship law as it stands in 2026, covering every major provision, the October 2025 amendment, the full naturalization requirements, and the implications for international professionals pursuing residency in Germany.

Legislative Overview: The StARModG

The Nationality Modernisation Act addresses what had been widely recognized as an outdated citizenship framework that failed to reflect Germany's demographic reality. With approximately 12 million foreign nationals residing in Germany (around 14% of the population), of whom 5.3 million had lived in the country for at least ten years, the previous system produced low naturalization rates: only 168,545 individuals applied for citizenship in 2022, representing just 3.1% of eligible long-term foreign residents.

The reform was designed to achieve three objectives: incentivize integration by shortening the path to citizenship, recognize Germany as a country of immigration by allowing dual nationality, and strengthen safeguards against those who reject democratic values. The Bundesrat approved the law on February 2, 2024, and its provisions apply prospectively from the date of entry into force (June 27, 2024).

Reduced Residency Requirement: 8 Years to 5

The most consequential change: the standard residency period required for naturalization was reduced from eight years to five years of legal residence in Germany. This provision applies to all foreign nationals who, on or after June 27, 2024, have accumulated five years of lawful residence. The reform does not apply retroactively; applicants who received their naturalization decision before the law's entry into force remain subject to the previous eight-year requirement.

For professionals entering Germany through the EU Blue Card, business residency, or freelancer residency pathways, this means the combined timeline from initial residence permit to citizenship eligibility is now five years, with permanent settlement (Niederlassungserlaubnis) achievable even earlier (21 to 27 months for Blue Card holders).

October 2025 Amendment: Three-Year Fast-Track Rescinded

The original 2024 reform included a provision allowing naturalization after just three years for individuals demonstrating exceptional integration: outstanding professional achievement, active community volunteering, C1-level German language proficiency, and complete financial self-sufficiency.

On October 8, 2025, the Bundestag passed legislation amending the Citizenship Act (Drucksache 21/1634), removing this accelerated pathway. The vote passed with 450 in favour, 134 against, and 2 abstentions. Interior Minister Alexander Dobrindt stated that the amendment was intended to reinforce the distinction between residency and citizenship, ensuring naturalization reflects sustained integration. The CDU/CSU and SPD supported the removal, while the Greens and Left Party opposed it.

As of 2026, five years is the minimum residency period for all naturalization applicants without exception. All other provisions of the 2024 reform, including dual citizenship and the reduced residency period, remain in full force.

Unrestricted Dual Citizenship

Prior to the reform, Germany generally required applicants to renounce their existing citizenship upon naturalization, with exceptions for EU citizens and cases where renunciation was legally impossible. The StARModG eliminated this requirement entirely. Since June 27, 2024, foreign nationals may naturalize as German citizens while retaining their existing nationality without restriction. German citizens may also acquire any foreign nationality without losing their German citizenship; the previous requirement for a Beibehaltungsgenehmigung (permission to retain citizenship) has been abolished.

The reform also eliminated the Optionspflicht (obligation to choose) for individuals who acquired German citizenship by birth in Germany to foreign parents: they are no longer required to decide between their German and foreign nationality upon reaching adulthood.

This provision has particular significance for nationals from countries that do not permit renunciation of citizenship, or where the renunciation process is impractical. It removes what had been one of the most significant barriers to naturalization for many long-term residents.

Birthright Citizenship for Children

Children born in Germany to foreign parents now automatically receive German citizenship at birth if at least one parent has been legally resident in Germany for five or more years (reduced from eight) and holds a permanent right of residence. Combined with the abolition of the Optionspflicht, these children can hold both German and their parents' nationality indefinitely without any obligation to choose.

Full Naturalization Requirements (2026)

Facilitations for Specific Groups

The reform includes targeted facilitations. Former guest workers (Gastarbeiter) and contract workers receive relief from certain naturalization requirements, including eased language requirements, in recognition of their long-standing contributions. Applicants over 67 may take an oral language test instead of the written exam. The security clearance process has been digitized and expanded to include additional security agencies.

Exclusion Criteria and Safeguards

The reform strengthened the values-based requirements for citizenship. The following are explicit grounds for exclusion from naturalization:

Criminal convictions related to antisemitic, racist, xenophobic, or inhumane acts are disqualifying. The commitment to Germany's constitutional values has been expanded to explicitly include acknowledgment of Germany's historic responsibility for the National Socialist dictatorship and its consequences, the protection of Jewish life, and the ban on wars of aggression. The security clearance process has been expanded to include agencies involved in residence and refugee law participation procedures, broadening the scope of background verification.

Frequently Asked Questions

Conclusion

The Nationality Modernisation Act represents a fundamental shift in Germany's approach to citizenship, balancing liberalization (shorter residency requirements, dual nationality) with strengthened safeguards (expanded exclusion criteria, enhanced security screening). The October 2025 amendment, removing the three-year fast-track, reflects the current government's emphasis on ensuring that naturalization follows a sustained period of integration.
