Yes, since 1 January 2019, people who have been granted asylum in Switzerland (B refugee permit), those provisionally admitted as refugees (F refugee permit), as well as other foreigners admitted on a temporary basis (F permit) may engage in a gainful activity as soon as this activity has been reported to the Employment Service (SDE).
The employer is responsible for announcing the start and end of the gainful activity through the required form
to be sent to the following e-mail address: emploi.asile.spop(at)vd.ch
The announcement must precede the start of the activity. However, the latter may begin as soon as it has been announced, without having to wait for a response from the administration.
