How long is the L permit in the Canton of St. Gallen?

The overall maximum duration of the L permit is set at twelve months by the federal provisions on short-term permits, applicable throughout Switzerland. The title remains closely linked to the employer who submitted the application and the specific activity for which it was issued.

When is it possible to extend the L permit?

The extension is allowed only in exceptional circumstances provided for by federal legislation, usually linked to particular personal situations or objective reasons that can be documented.

How do I switch from permit L to permit B?

The transition to permit B requires an application from scratch and an employment relationship of more than one year or indefinitely. The application must be submitted before the expiry of the L permit to avoid an interruption of the residence permit, with updated documentation on work, accommodation and means of subsistence.

What practical requirements must those who obtain an L permit do?

The worker must take out LAMal health insurance within three months, register with the Municipality of residence, open a bank account if necessary and verify enrollment in the AVS/AI/IPG and AD/AC contributory scheme through the employer. The LPP applies from the moment the coordinated salary exceeds the entry threshold provided for by law.

What happens if the contract ends within twelve months?

If the employment ends within twelve months, the L permit automatically ceases and residence in Switzerland is no longer allowed, unless the worker has accrued a right to a different title. It is therefore necessary to leave the country, unless the procedure for a B permit is opened before the expiry date.

The short-term L permit is one of the residence permits provided for by Swiss federal legislation on foreigners. It is issued by the competent cantonal authorities — in the case of the Canton of St. Gallen by the cantonal office in charge — under the supervision of the State Secretariat for Migration (SEM). Its total maximum duration is set at twelve months, as established by the federal provisions on short-term permits applicable throughout Switzerland.

This residence permit is distinguished from the

Operational details

Obtaining an L permit in the Canton of St. Gallen means accepting a series of stringent constraints that clearly differentiate this title from the B permit. The most relevant is the link with the individual employer: those who change jobs during the validity of the permit must resubmit an application, with times and costs that start from scratch. The same applies to those who move from one activity to another, even within the same company.

Maximum duration and extension: the actual margins

The total duration of the L leave may not exceed twelve months. The extension is allowed only in exceptional circumstances provided for by federal legislation: these are limited cases, usually linked to particular personal situations or to objective reasons that can be documented. In the practice of the Canton of St. Gallen — as in the rest of Switzerland — the granting of an extension is not automatic and requires a new investigation by the cantonal authority.

When the employment is extended beyond the year, it is not possible to extend the L permit: the change to a different title requires a new application. This step is technically distinct from the “extension” and is subject to different criteria, related to the nature of the new employment relationship.

Moving to permit B: conditions and differences

Key points

To navigate the procedures for the L permit in the Canton of St. Gallen, it helps to follow an orderly path. The relevant cantonal office publishes the operational information and the required forms on its website; the documentation needed varies depending on nationality and the expected duration of the employment relationship.

Step-by-step procedure

The first step is the submission of the application by the employer to the cantonal migration authority. The application must be accompanied by the signed employment contract, a description of the planned activity, the worker's identification details, and proof of accommodation. Once the application is received, the cantonal office checks that the admission conditions are met and, if applicable, forwards the file to the SEM for consultation.

After approval, the worker is called in for the collection of biometric data and the issuance of the permit. From that moment, the maximum twelve-month validity period begins.

If the contract is nearing expiry

Before the contract expires, the worker and the employer must assess the situation. If the employment ends within the twelve months, the L permit expires automatically; staying in Switzerland is no longer permitted and the worker must leave the country, unless the worker has acquired the right to a different status.

If, on the other hand, the employment relationship continues beyond the year or turns into a permanent contract, the procedure for issuing a B permit begins. The application must be submitted before the L permit expires to avoid any interruption in the residence status.
