Switzerland's Stricter Naturalisation Law (2018)
Switzerland significantly tightened its naturalisation requirements in 2018, demanding a C permit, demonstrating successful integration, and specific language skills.
Effective January 1, 2018, Switzerland implemented a major revision of its Federal Act on Citizenship, making the path to ordinary naturalisation considerably more rigorous. This legislative overhaul introduced several key changes that continue to shape the naturalisation landscape.
One of the most significant amendments requires applicants to hold a "C" settlement permit (permis d'établissement) rather than a "B" residence permit (permis de séjour). While the official federal residency requirement for naturalisation was reduced from 12 to 10 years, the prerequisite of holding a C permit—which typically takes 5 to 10 years of continuous residency to obtain—means that for many, the practical waiting period before even being eligible to apply has effectively increased. This change underscores a move towards ensuring long-term stable residency prior to citizenship consideration.
Beyond the permit status, the new law places a strong emphasis on successful integration. Applicants must demonstrate a deep understanding of Swiss customs and traditions, respect the Swiss legal order, and pose no threat to Switzerland's internal or external security. Financial self-sufficiency is also paramount; individuals who have received social assistance in the three years prior to their application, or during the application process itself, are generally ineligible. Furthermore, adequate proficiency in a national language (German, French, or Italian) at level B1 spoken and A2 written is now a mandatory requirement. This comprehensive reform aimed to ensure that new citizens are genuinely integrated into Swiss society before acquiring nationality, reflecting a clear policy shift towards higher standards for citizenship acquisition.
