Each canton is different and I received Swiss citizen ship last year in the Canton of Vaud, where it not nearly so complicated. No classes, no language tests (although your application has to be in French and you have to prove your fluency). I had one interview at home with a police man from Nyon and one interview at the commune with three people from the administration - very relaxed and informal. The application for myself and my daughter was much less expensive than in Berne and the ceremony in Lausanne took place just under two years after my application was submitted. Easy peasy. I am delighted to be Swiss and feel it adds considerably to my integration and the stability of my daughter who is no longer a “foreigner” in our village.
