I have a work authorization for Switzerland valid until 19th April 2018 for 4 months max.
I intended to get a short-stay work visa for 120 days (Type D visa) but due to an incorrect appointment at VFS, I received a short-stay business visa (Type C) for 90 days only, even though I had sent my work authorization letter with the application.
I want to know how I can cancel this business visa and how I can get the work visa for 120 days since I have a valid Swiss work authorization letter and I have not yet travelled.
Please help. Let me know if you need more details.
