Competent office: Migration Office of the Canton of Basel-Country
Variable duration: Depends on nationality and individual situation
Difference from permit C: B is renewable, C (domicile) requires 10 years residence

The B permit is the residence permit for foreigners who intend to reside in Switzerland on a continuous basis. Unlike the L permit, which has a maximum validity of 1 year and is intended for short stays, the B permit is explicitly renewable and offers a stable legal basis for those who decide to live and work in the country on a medium-long horizon.

The management of residence permits is entrusted to the State Secretariat for Migration (SEM) at the federal level, but each canton has its own migration office that processes applications and renewals in the territory.

For EU/EFTA citizens, the B permit is usually easier to renew than non-EU citizens, as they benefit from the free movement guaranteed by the agreement on the free movement of persons. Non-EU citizens, on the other hand, must demonstrate that they continue to meet the admission requirements (valid employment contract, sufficient funds, etc.) at each renewal.

Differences with the C permit and path to naturalization

It is essential to clarify that permit B is not automatically a step towards permit C (domicile). However, the C permit remains the long-term goal for those who intend to settle permanently in Switzerland. According to federal rules, ordinary naturalization requires the possession of a C permit and at least 10 years of residence in Switzerland (the period can be shortened to 8–18 years according to cantonal law, but for the purposes of renewal these years count double for some purposes).
