Operational details

The practical analysis of the short-term L permit in the Canton of Aargau requires an understanding of the dynamics between federal law and cantonal directives. Unlike B residence permits, which offer greater stability and are generally renewable for longer periods, the L permit is designed for temporary situations. Holders of an L permit must be aware that their status is strictly tied to their employer. This means that in the event of a termination of the employment relationship, the validity of the permit may be reassessed. At the national level, the Swiss system does not provide for a federal minimum wage, however, in sectors where collective labor agreements (CLA) or standard employment contracts (SEC) are present, wage conditions must be guaranteed even for temporary permit holders.
