Facilitated naturalisation offers foreign spouses of Swiss nationals an accelerated and simplified route to Swiss nationality. It is based on close family ties with Switzerland and aims to strengthen the unity of the household. PBM Avocats accompanies you through all the stages of this procedure in Geneva and Lausanne.
The Legal Basis: Art. 21 of the Nationality Act (SNA)
Art. 21 SNA opens the right to facilitated naturalisation to the foreign spouse of a Swiss national. This route is distinguished from ordinary naturalisation (art. 9 SNA) by lighter conditions — notably in terms of residence duration — and by a procedure centralised at the federal level (FSMI), without passage through the municipalities and cantons.
| Condition | Facilitated naturalisation (art. 21 SNA) | Ordinary naturalisation (art. 9 SNA) |
|---|---|---|
| Duration of residence in Switzerland | 5 years | 10 years |
| Connection to a Swiss citizen | Marriage to a Swiss national (3 years) | Not required |
| Procedure | Federal (FSMI only) | Federal + cantonal + municipal |
| Duration of proceedings | 1 to 2 years | 2 to 4 years |
| Estimated cost | CHF 900 (federal fee) | CHF 900 + cantonal and municipal fees |
The Cumulative Conditions of Art. 21 SNA
1. Five Years of Regular Residence in Switzerland
The foreign spouse must have legally resided in Switzerland for at least 5 years in total before filing the application. Years of legal residence are those during which the applicant held a valid residence permit (B, C or other). Years spent abroad interrupt the count but are not erased — only recent continuity is important.
2. Three Years of Marriage to a Swiss National
The couple must have been married for at least 3 years at the time of filing the application. The 3-year count begins on the date of the official marriage, not the date of the religious ceremony or of cohabitation before the marriage. The marriage must have been celebrated in a form recognised by Swiss law (civil marriage or foreign marriage recognised in Switzerland).
3. Effective Cohabitation
The spouses must lead an effective life together at the time of filing the application and until the final decision. A de facto separation, even without divorce, excludes facilitated naturalisation. Temporary professional absences (expatriation for work, business trips) do not constitute a break in cohabitation if the family home remains in Switzerland.
4. Successful Integration
The integration criteria are similar to those for ordinary naturalisation (art. 12 SNA):
- Sufficient knowledge of a national language (B1 oral)
- Respect for the Swiss legal order
- Absence of threat to public security
- Financial independence (no dependence on social assistance)
- Participation in social life
The Facilitated Naturalisation Procedure
- Step 1: Assembly of the file (FSMI form, identity documents, marriage certificate, residence certificate, criminal record extract, language and integration supporting documents)
- Step 2: Filing with the FSMI (State Secretariat for Migration), Berne
- Step 3: Examination of the file by the FSMI — possible separate interviews of the spouses
- Step 4: FSMI decision
- Step 5: Oath-taking in the municipality of domicile
Particular Case: Naturalisation after Divorce or Death of the Swiss Spouse
Art. 21 para. 2 SNA provides that facilitated naturalisation may also be granted after the dissolution of the marriage (divorce or death of the Swiss spouse), if the applicant has already held Swiss nationality or if one of their parents or grandparents was Swiss. PBM Avocats analyses these particular situations on a case-by-case basis.

Frequently Asked Questions on Facilitated Naturalisation for the Spouse of a Swiss National
What are the conditions for facilitated naturalisation as the spouse of a Swiss national?
Under art. 21 SNA, the foreign spouse of a Swiss national may apply for facilitated naturalisation if they cumulatively satisfy: (1) 5 years of regular and authorised residence in Switzerland in total; (2) 3 years of marriage to a Swiss national; (3) successful integration (national language, respect for the legal order, financial independence); and (4) effective cohabitation with the Swiss spouse at the time of the application and the decision. The marriage must be genuine — not a marriage of convenience.
Must the couple still be living together at the time of naturalisation?
Yes, this is an imperative condition. Effective cohabitation with the Swiss spouse must exist both at the time of filing the application and at the time of the FSMI decision (art. 21 para. 1 SNA). If the couple is separated, in divorce proceedings or if cohabitation has ceased, facilitated naturalisation cannot be granted. A separation occurring after the decision but before the oath-taking may also pose a problem. PBM Avocats advises you on the optimal timing of your application.
What is a marriage of convenience and how do the authorities detect it?
A marriage of convenience is a marriage concluded solely for the purpose of obtaining a migration advantage (residence permit or naturalisation) without any genuine intention of leading a life together. The FSMI authorities examine indicators such as: the mutual knowledge of the spouses, the brevity of the relationship before the marriage, significant age differences, the absence of a common language, contradictions in the spouses' accounts during separate interviews, or the payment of money. If a marriage of convenience is suspected, criminal proceedings may be initiated.
Is facilitated naturalisation possible for registered partners?
Yes. Since the entry into force of the Registered Partnership Act in 2007 and, more recently, the opening of civil marriage (2021), registered partners of a Swiss national enjoy the same rights to facilitated naturalisation as spouses. The conditions are identical: 5 years of regular residence in Switzerland, 3 years of partnership or marriage, successful integration and effective cohabitation. PBM Avocats handles applications for all couple configurations.
Is facilitated naturalisation faster than ordinary naturalisation?
Yes, generally. Facilitated naturalisation (art. 21 SNA) is a federal procedure centralised at the FSMI, without the municipal and cantonal stages of ordinary naturalisation. The procedure generally takes 1 to 2 years. Moreover, the conditions are less restrictive: 5 years of residence in Switzerland are sufficient (compared to 10 years for ordinary naturalisation), without the strict requirements of the municipalities. However, the criterion of effective cohabitation is specific to this route and must be carefully documented.
