What is the difference between permit B and permit C?

The B permit is temporary and renewable (duration 1-5 years) for those working in Switzerland. The C permit is permanent and can be obtained after 10 years of ordinary residence in Switzerland, or after 5 years if you are an EU/EFTA citizen. Unlike the B permit, the C permit does not require renewal and is not bound by the continuity of the employment contract.

By when do I need to apply for a B permit renewal?

Renewal must be requested 2-3 months before the expiration date. If the permit expires without renewal, the worker loses the legal right to reside and work in Switzerland. The employer must submit an updated application to the cantonal migration office with confirmation of the valid employment contract and proof of maintenance of the accommodation.

Is LAMal health insurance mandatory?

Yes, enrollment in health insurance (LAMal) is mandatory and must occur within 3 months of arrival in Switzerland. It is a binding prerequisite for obtaining and maintaining permit B. Without active coverage, the cantonal migration office may reject the renewal application. Awards vary by canton and age group.

If I change employers, what should I do?

If you change employer during the validity of permit B, you must apply for a change authorization at the cantonal migration office. This DOES NOT happen automatically. The new employer must submit a new declaration and sometimes a certificate of suitability for the position. Until the change is released, you have no right to work for the new employer.

Permit B: The legal basis of temporary work in Switzerland

The administrative management of permits follows a typically Swiss federalist system. The Secretariat of State

The B permit in everyday life: Rights, obligations and access to services

The B permit is not only a bureaucratic practice, but the key that enables legal work, access to social security, payment of taxes and the right to sign rental contracts and financial services in Switzerland. Without this document, any work activity is prohibited and exposes you to administrative sanctions and possible removal from the territory.

Once the B permit is obtained, the worker becomes subject to all Swiss tax obligations. Registration to the AVS/AI/IPG (the pension system for old age, invalidity and earnings allowance) is automatic and compulsory. The contribution paid by employees is equal to 5.3% of the gross salary, to which is added an identical contribution paid by the employer, for a total of 10.6%. Alongside this, the worker is enrolled in the daily allowance (AD) and accident insurance (AC) system, with overall rates of 1.1% up to a set annual ceiling. Add to this the federal, cantonal and municipal taxes, calculated according to the three levels of the Swiss state: each canton has its own cantonal rate, and each municipality applies a multiplier on a cantonal basis.

Health insurance (LAMal) is mandatory for all residents, regardless of the type of permit. The awards are individual, vary by canton and age group, and DO NOT

Step-by-Step Procedure: How to Request It and Which Documents You Need

The request for a Permit B begins when a candidate signs an employment contract with a company registered in Switzerland. It is the employer who, except in cantonal exceptions, submits the application to the cantonal migration office of the canton where the work will be performed. In cantons with advanced digital infrastructure, the procedure takes place entirely online through dedicated cantonal platforms; in others, physical copies and attachments are still required.

The essential documents to gather include: a valid passport or an internationally recognized identity document; the original employment contract or an authenticated copy (it must clearly indicate duties, salary, hours, and duration); proof of accommodation (lease agreement, letter of hospitality from friends or family, or reservation at a temporary facility if you do not yet have a fixed residence); the completed official application form (downloadable from the cantonal migration office website); and, for citizens of third countries, sometimes a statement from the employer attesting to the specificity or necessity of the role and the impossibility of finding candidates with work rights already present in Switzerland.

Processing times vary considerably between cantons, usually between 2 and 8 weeks. During this waiting period, the worker does not yet have the formal right to work; however, some cantons allow the start of activity 'under reservation', i.e., while awaiting the official release of the permit. This practice varies by canton and professional sector.
