Can a non-EU worker eventually get permanent residence (C permit) in Switzerland?

A work permit can lead to permanent settlement. Most third-country nationals become eligible for the Settlement Permit C after ten years of orderly, uninterrupted residence, provided integration criteria are met. For long-term stays, the authorities weigh professional and social adaptability, language skills and age. Proof of national-language knowledge at the required level is needed, and good integration (no reliance on social assistance, respect for public order) is expected. The C permit then gives free labour-market access and is no longer tied to a single employer.
