Germany's citizenship landscape has undergone a dramatic transformation. According to data compiled by Welt am Sonntag, at least 309,852 individuals acquired German passports in 2025, surpassing the previous all-time high of nearly 292,000 set just one year earlier.
The data covers 14 of the country's 16 federal states, with some figures based on preliminary numbers. Mecklenburg-Vorpommern and Saxony-Anhalt have yet to report, while Lower Saxony, Saarland and Schleswig-Holstein provided only partial data, meaning the true nationwide total is likely higher still.
Two major policy shifts introduced in mid-2024 have fueled this wave. The minimum residency requirement for citizenship was cut from eight years to five, and Germany began formally permitting dual citizenship, removing the obligation for applicants to renounce their original nationality. Together, these reforms opened the door for hundreds of thousands of long-term residents who had previously been ineligible or unwilling to apply.
The timing also matters. Many refugees who arrived during the 2015–2016 migration wave, particularly from Syria, have now lived in Germany long enough to qualify under the new rules. In 2024, Syrians accounted for 28% of all new citizenships, making them the largest group, followed by Turkish nationals. While the 2024 figures represented a 46% year-on-year jump, the pace of growth slowed in 2025 to around 6%.
The capital has emerged as the epicentre of the naturalisation trend. Berlin processed 39,034 naturalisations in 2025, nearly doubling its 2024 figure of 21,811. Hamburg similarly reached a new high with 11,532 new citizens, up from 9,599 the year before.
Other major cities and states saw notable gains as well. Brandenburg recorded 4,695 new citizenships, a 25% increase over the previous year. Cologne's naturalisations more than doubled, rising from roughly 3,400 to 7,000. Munich recorded 7,549, a modest but steady increase from 6,747 in 2024. Frankfurt, however, bucked the trend entirely, with figures holding virtually flat,m roughly 4,000 in 2024 and 3,913 in 2025.
Beyond Syrian nationals, two other groups stand out. Naturalisations among Turkish citizens have accelerated considerably, aided by the new dual citizenship provisions that now allow them to retain their Turkish passports. Russian nationals are also applying in growing numbers. In North Rhine-Westphalia alone, 3,841 Russians became German citizens in 2025, a jump of 67.4 percent. Analysts attribute this partly to professionals seeking political stability and legal security in Western Europe.
Although some municipalities report a temporary slowdown in new applications, authorities are already bracing for the next major wave. Ukrainian refugees who arrived in early 2022 will reach the five-year residency threshold by spring 2027, just as their collective temporary protection status is set to expire in March of that year.
Unlike earlier refugee cohorts, Ukrainians benefited from considerable structural advantages, including permission to immediately find employment and receive full residency status, positioning many of them to meet citizenship criteria more quickly. That said, applicants must still fulfil core requirements, including the ability to support themselves financially.
Germany's naturalisation boom signals a fundamental shift in how the country integrates its foreign-born population. With the current coalition government maintaining the reformed citizenship rules, the upward trajectory looks set to continue well beyond 2025.
