Key facts

• What: Short-term permit L to work in Switzerland
• Maximum duration: Up to 1 year (renewable)
• Where: Canton Vaud and all Swiss cantons
• Who: Foreigners who sign a work contract in Switzerland
• Validity: Linked to the persistence of the employment relationship with the indicated employer

The short-term permit L is one of the most common work permits in Switzerland and is issued by the State Secretariat for Migration (SEM) upon request from the competent canton. In Canton Vaud, as in all other Swiss cantons, the permit L represents the solution for foreign workers who wish to carry out a professional activity on a temporary basis, without a long-term commitment.

According to Swiss federal regulations, the permit L has a maximum validity of 1 year and is renewable if the conditions that generated it continue to exist. This means that if the employment contract continues or is renewed, it is possible to request the extension of the permit L under the same conditions.

What is the short-term permit L?

The permit L is a document that authorizes a foreigner to work in Switzerland for a limited duration, determined by the employment contract and the needs of the employer. It is not a permanent residence permit, but a temporary solution designed to meet specific and time-limited work needs.

Operational details

Maximum duration and extension conditions

The L permit remains valid for the entire duration of the employment contract and in any case up to a maximum of 1 year. If the work continues beyond this period — for example, because the contract is renewed or transformed into a permanent position — it is necessary to request an extension of the L permit or to consider switching to a different category permit, such as the B permit.

The request for an extension of the L permit follows the same procedure as the initial one: the employer submits the updated documentation (new contract, certificates of employment continuity) to the canton, which transmits it to the SEM. The decision to renew depends on the persistence of the original conditions — in particular, the confirmation of the employment relationship and the absence of reasons for objection at the federal or cantonal level.

It is important to note that the L permit is not automatically renewed: each extension requires an explicit request and a new evaluation by the authorities. Processing times vary depending on the administrative workload of the canton and the completeness of the documentation provided.

Transition from L permit to B residence permit

After a certain period of continuous work in Switzerland, the worker with an L permit may be eligible to apply for a transition to the B residence permit. The B permit is renewable and is generally granted for periods of 5 years, offering greater stability and broader rights compared to the L permit.

Procedure for requesting and required documentation

To obtain the L permit in the Canton of Vaud, the procedure always starts with the employer. It is not the foreign worker who submits the application directly to the SEM, but the company that intends to hire them in Switzerland.

The employer must collect the following documents and submit them to the cantonal employment office (or the competent office for work permits in the Canton of Vaud):

• Signed employment contract between the employer and the foreign worker, including duration, duties, salary, and start date
• Employer's declaration attesting to the need to hire a foreign worker (reasoning, search for Swiss/UE candidates)
• Copy of the worker's passport or identity document
• Certificate of good conduct (if the worker has a criminal record)
• Employer's tax declaration and proof of the company's financial stability (in some cases)

The canton evaluates the documentation within a few working days and, if everything is in order, sends it to the SEM. Approval from the SEM usually arrives within 2-3 weeks, unless further clarification is requested.

Deadlines and renewal of the permit

Once the L permit is obtained, it remains valid for the duration of the employment contract, up to a maximum of 1 year. Before the expiration date, if the employment relationship continues, the employer must submit a renewal request with at least 4-6 weeks' notice (exact times vary by canton).

During the stay in Switzerland with an L permit, the worker is subject to all Swiss tax and contribution obligations, including mandatory enrollment in health insurance (LAMal) within 3 months of arrival. Additionally, AVS/AI (pension) contributions, LAMal premiums, and federal, cantonal, and communal taxes are due regardless of the temporary nature of the permit.
