Swiss Nationality Law governs the acquisition and loss of Swiss nationality. Individuals can obtain nationality through birth, marriage, or naturalization. Children born to at least one Swiss parent automatically acquire nationality, while foreign nationals can apply for naturalization after residing in Switzerland for a specific period, typically 10 years. The law also outlines the conditions under which nationality can be revoked, such as criminal activity or failure to fulfill residency requirements. Swiss nationality is important for participation in civic life, including voting and holding public office, reflecting the country's commitment to integrating residents into its society.
