Swiss Citizenship

April 20, 2026

There are three main ways to acquire Swiss nationality: by birth, through marriage (not automatically), or by naturalization.

This section focuses on those wishing to obtain Swiss citizenship — a process that can often take considerable time and preparation.

Citizenship by Birth

Unlike countries such as the United States, Switzerland does not grant citizenship based on birthplace alone. A child automatically becomes Swiss if their married parents include at least one Swiss citizen.

If the parents are not married, a child born to a Swiss mother is also automatically Swiss. In cases where only the father is Swiss, citizenship can be obtained if he legally recognizes the child before the child reaches adulthood.

Switzerland permits dual or multiple citizenships, so whether a naturalized Swiss citizen may retain their previous nationality depends on the laws of their other country.

Regular Naturalization

Foreign nationals who do not have Swiss ancestry or family connections can apply for citizenship through regular naturalization.

To qualify, an applicant must:

Have resided in Switzerland for at least 10 years continuously.
Count double the years lived in Switzerland between the ages of 10 and 20.
Have lived in their current municipality for a set period, typically 2 to 5 years, depending on local rules.

Applicants are required to hold a C residence permit and demonstrate proficiency in one of Switzerland’s national languages — at least B1 in spoken and A2 in written form.

People receiving welfare or those with criminal records are generally not eligible.

The State Secretariat for Migration (SEM) evaluates whether applicants are:

Well integrated into Swiss society,
Knowledgeable about Swiss traditions and customs,
Respectful of Swiss laws, and
Not a threat to national security.

Once the SEM approves an application to move forward, the cantonal and municipal authorities conduct their own reviews, which may include interviews or local-level evaluations.

The naturalization process varies greatly across cantons and communes. Some municipalities require candidates to pass a written or oral test on Swiss civics, while others decide by community vote.

Processing time typically ranges from 12 to 18 months, and the cost is usually between CHF 2,500 and CHF 3,500 per person, though it depends on the canton and commune.

Facilitated Naturalization

Certain individuals — such as foreign spouses of Swiss citizens or children of Swiss parents who are not yet Swiss — may qualify for facilitated naturalization, a faster and less complex route.

To be eligible, applicants must be well integrated, law-abiding, and pose no security risks. Unlike regular naturalization, cantons and municipalities cannot add extra conditions, though they may appeal a federal decision.

Generally, a foreign spouse may apply if:

They have been married to a Swiss citizen for at least three years, and
Have lived in Switzerland for a total of five years, including the year immediately before applying.

People living abroad who have strong personal ties to Switzerland may also qualify, provided they have been married to a Swiss citizen for at least six years, and the Swiss spouse already held citizenship before the marriage.

Children under 22 years old who did not obtain Swiss nationality when their parents did can apply separately if they have lived in Switzerland for at least five years.

Third-Generation Immigrants

Following a 2017 national referendum, Switzerland extended the facilitated process to third-generation immigrants.

To qualify, candidates must:

Have been born in Switzerland,
Be between 9 and 25 years old,
Hold a C residence permit, and
Have completed at least five years of schooling in Switzerland.

Their parents must have:

Lived in Switzerland for at least 10 years,
Completed five years of Swiss schooling, and
Held a valid residence permit.

Additionally, at least one grandparent must have been either born in Switzerland or have held a Swiss residence card.
