If the trainee/intern wants to continue their traineeship/internship longer than their permit is valid, they can apply to extend the permit. The trainee/intern may be granted a residence permit for one or more periods, but these periods can total no more than 18 months.
The employer starts the application
For an employer, the process of applying for an extended residence permit for a traineeship/internship is the same as a first-time application. You start the application by providing information about the employment in the e-service. When you are finished, the trainee/intern receives a link to the e-service, where they fill in their information and submit the application thus completing the process. Only then is the application registered with the Swedish Migration Agency.
