Has anyone had an non-EU L-permit renewed recently? If so how long did it take to receive the renewal.
Also, I have some upcoming travel foreign travel. If the new card does not arrive in time is it possible to get permission from the Kreisburo to reenter Switzerland?
Yes. But mine may have been a special case as I was moving from B to L. I know that the Amt fur Wirtschaft und Arbeit approved it in 2 weeks, but the cantonal immigration decided to sit on it for 6 weeks.
For the Rückreisevisum, remember to give them sufficient information - e.g., the dates, where you will be travelling to, single entry/multiple entry etc. Also take a passport-sized photo with you and the fees for the visa.
