Swiss Residence Permit Types: B, C, L, G and Ci Explained

Switzerland does not issue one generic "residence permit". It issues a defined set of permit categories, each identified by a letter, and the letter on your card determines almost everything that matters: the length of stay, the right to take a job or run a business, the rules on family reunification, and the path toward permanent settlement and eventually citizenship. The everyday letters are L (short stay), B (residence), C (settlement), Ci (residence with gainful employment) and G (cross-border commuter), with the protection permits S, F and N completing the set. The State Secretariat for Migration (SEM) sets the federal rules, while the cantonal migration offices administer applications in practice.

The single biggest dividing line is whether you hold an EU or EFTA passport. Nationals of EU and EFTA states move under the Agreement on the Free Movement of Persons and receive permits almost as a formality, without quotas. Everyone else is a "third-country national" and faces annual federal quotas, a labour-market test and a higher evidential bar. This guide sets out each permit type, who qualifies, how the categories connect, and which letter a relocating founder actually needs.

Every Swiss permit answers four questions: who it is for, how long it lasts, whether you can work, and whether it leads to settlement. The table sets out the everyday categories side by side; the sections below take each letter in turn. The letters L, B and G behave differently for EU/EFTA nationals and for third-country nationals, so read those rows together with the regime split that follows.

Permit	Who it is for	Duration	Work rights	Path to C
L	Short-term stay, fixed purpose	3 to 12 months, extendable to 24	Tied to the named contract	No (temporary status)
B	Longer-term residence, work or means	EU/EFTA 5 years; third-country 1 year, renewed annually	Yes, for the stated purpose	Yes, after 5 or 10 years
C	Settled residents	Permanent (card reissued every 5 years)	Unrestricted	Is the settlement permit
Ci	Family of diplomats and IGO staff	Length of the principal's posting	Gainful employment allowed	Treated separately
G	Cross-border commuters	EU/EFTA 5 years; third-country 1 year	Work in Switzerland, live abroad	Not a residence permit
S / F / N	Protection and asylum	Temporary, situation-dependent	Varies, subject to notification	Separate regime

The numbers above are the general position under SEM and ch.ch guidance; treaty-specific and nationality-specific details are set out under each permit below. For the mechanics of applying and registering, see our residence permit guide.

The L permit (Kurzaufenthaltsbewilligung) covers stays of a limited, defined duration, typically under twelve months. It is issued for a specific purpose such as a fixed-term assignment, a short employment contract, a project posting or a course with a set end date. As a rule the L permit runs for 3 to 12 months and can be extended to a maximum of 24 months. It is tied to the job or purpose for which it was granted, so changing employer or activity usually means a fresh application rather than a simple transfer.

For EU and EFTA nationals, a short-term L permit is the standard document where the employment contract runs from three to twelve months under free movement. For third-country nationals, the L permit is drawn from the federal short-stay quota and requires the same labour-market justification as a longer residence permit. Holders are generally taxed at source (Quellensteuer). An L permit can in some cases be converted into a B permit, but it is designed as a temporary status and does not, on its own, count toward the residence period that leads to settlement.

The C permit (Niederlassungsbewilligung) is the settlement permit. It is open-ended, not tied to a particular job, and removes most labour-market restrictions: a C holder may change employer, become self-employed or stop working without affecting their status, and a spouse benefits from the same freedom. Settlement is the closest position to a Swiss national short of citizenship. The plastic card is reissued every five years for control purposes, but the underlying status is permanent and is not renewed on conditions.

Crucially for tax, C holders leave the source-tax system: they file ordinary annual tax returns like Swiss citizens, in contrast to B, L and G holders who are taxed at source. The C permit is also the prerequisite for ordinary naturalisation, which is why it functions as the gateway between long-term residence and Swiss citizenship.

The Ci permit is a narrow category for the spouses and children of members of foreign diplomatic missions, consular posts and international organisations based in Switzerland, as well as certain staff of those bodies. Switzerland hosts a large concentration of international institutions, particularly in Geneva, so the Ci permit is far more common there than elsewhere.

Its distinguishing feature is that it allows the family member to take up gainful employment in Switzerland during the period the principal is posted, which diplomatic status would otherwise restrict. The Ci permit is linked to the principal's assignment: it lasts as long as that posting and ends when it does. It is a purpose-specific status rather than a step on the residence ladder, so time on a Ci permit is treated differently from ordinary B-permit residence when settlement is later assessed. Competitor explainers often omit it; including it completes the picture.

Three further permits exist for protection and asylum. They are not relocation or business-immigration routes, but they are part of the same letter system, so a complete answer names them. The S permit grants temporary protection to people in need of collective refuge, activated by the Federal Council rather than through the individual asylum procedure. It was used at scale from 12 March 2022 for people fleeing the war in Ukraine, with the protection regime extended by Federal Council decision and kept under regular review. S holders may take up employment subject to notification.

The F permit is for people who are provisionally admitted, meaning a removal order cannot currently be enforced, so they may remain on a temporary basis. The N permit identifies asylum seekers whose application is still being processed. Founders and employees moving to Switzerland for work will not use any of these categories; they are included here only to close the taxonomy.

The right starting permit depends on how you intend to live and work in Switzerland, not just on the company you set up. Owning Swiss shares or being a director does not by itself grant any permit. The common founder cases map cleanly onto three letters:

• Relocating owner-manager → Permit B. A founder who moves to Switzerland to run a GmbH or AG needs a B permit. EU/EFTA founders obtain it under free movement; third-country founders must secure a quota place and prove an economic interest to Switzerland, sequenced alongside the incorporation.
• Cross-border director → Permit G. A founder who keeps their home in a neighbouring country and commutes to direct a Swiss company uses a G permit, with the weekly-return rule and source-tax treatment that come with it.
• Short assignment → Permit L. A time-boxed project, secondment or pilot phase fits the L permit, which can later convert to a B if the role becomes permanent.

Because the permit and the company are separate steps that have to be timed together, founders usually run them in parallel. Our company formation and migration teams handle both sides, and if you are weighing where to base the business, low-tax options such as incorporating in Zug sit alongside the relocation decision. We work on a custom-quote basis, so talk to our team with your nationality and plans and we will scope the route.
