“Not possible” in the sense of employers having to do the whole process of applying for a B permit subject to quotas to hire a 3rd country national?
I guess the issue here is the idea of a S permit making the transition or application to B easier. I may be wrong, but I think the path from S to B simply doesn’t exist. The application for B starts from zero.
And, employers may be confused now. It was so easy to hire someone with an S permit. Applying for a B permit for 3rd country national requires knowledge within the organization to ensure a positive outcome. Some employers don’t have this knowledge and experience.
