Migration research: The SVR Migration scientifically explains the boom in naturalizations in Germany

Germany has been experiencing a noticeable shift in naturalization patterns for several years . With approximately 300,000 naturalizations in 2024, a new record high was reached. A recent research project by the Expert Council on Integration and Migration (SVR) reveals the underlying developments – and why refugees play a central role in this trend. The new report offers valuable insights for migration law practitioners, counseling centers, and applicants. We have summarized the key findings.

Why naturalization numbers are rising

Two developments characterize the current “naturalization boom”: People who have fled to Germany since 2014–2016 are increasingly fulfilling the requirements for naturalization , and refugees show an above-average propensity for naturalization.

For many Syrian, Afghan or Iraqi nationals, German citizenship is a crucial step:

• for long-term residency security

• to stable future and job market opportunities

• to recognize their integration achievements

• to social belonging

This trend shows that over time, naturalization is becoming a logical part of the integration process – not only politically desired, but also actively sought by many refugees.

Reasons for the increase in naturalizations since 2014

The data published by the Expert Council on Integration and Migration (SVR) reveals a clear trend: since 2014, the number of naturalizations has risen steadily , and since 2021, a large proportion of this increase has come from the countries of origin of refugees. Syrian nationals now account for a significant share of all naturalizations . The SVR's interactive graphics show in detail how different origin groups have developed – an important tool for anyone advising on or preparing decisions in the field of migration law.

The numbers didn't rise or fall randomly. Several events had a direct impact:

• Brexit : The United Kingdom's withdrawal from the EU led to a surge in naturalization applications from British citizens starting in 2016. This trend peaked in 2019.

• Coronavirus pandemic: The pandemic led to the temporary closure of citizenship offices, the rerouting of staff, and delays in processing applications.

• Reaching the minimum residency requirement from 2021 onwards: Many refugees from 2015 were able to be naturalized for the first time from 2021 onwards. This set a new dynamic in motion.

• Citizenship law reform 2024: This reform comprehensively modernized naturalization law for the first time in decades. In particular, the previously often restrictive prohibition of dual citizenship was abolished.

Conclusion: Reasons for the increase in naturalizations

The latest figures and analyses from the Expert Council on Integration and Migration (SVR) make it clear: The sharp increase in naturalizations in Germany is not a short-term spike, but rather an expression of long-term structural change. Refugees who came to Germany between 2014 and 2016 are increasingly coming into focus – not only because they meet the formal requirements, but because they are actively seeking German citizenship. Naturalization is thus becoming more than ever an integral component of successful integration. The data also show how closely migration policy developments – from Brexit to the COVID-19 pandemic and the reform of the Nationality Act – are linked to actual fluctuations in naturalization figures. For advisory practice, this means that naturalizations should not be understood as isolated administrative acts, but as the result of long-term legal, social, and individual developments. This new dynamic opens up opportunities – for applicants, for integration policy, and for a modern migration society that makes belonging visible and strengthens it.
