Descent (register before 25) · decided by SEM / Cantonal authority
Swiss citizenship by descent
Switzerland passes citizenship through a parent only — there is no grandparent route — and a citizen born abroad can lose it at 25 without registering. Check whether you qualify, build your lineage, and get a primary-source-backed document checklist and cost estimate.
Grandparent or great-grandparent claim? Complex chain? Skip the research — talk to a Switzerland citizenship specialist in 30 minutes.

🇨🇭 Through a Swiss parent
Switzerland passes citizenship parent-to-child — register before 25 if born abroad, or it can lapse.
Eligibility
Who may qualify
A Swiss parent at your birth → Swiss by descent (Art. 1 BüG).
No grandparent route — transmission is parent-to-child each generation.
Born abroad with another nationality? Register (or declare to retain) before age 25 or you forfeit it.
A parent who already forfeited at 25 can't pass it on.

Why Switzerland
What makes Switzerland different
Parent route only — no grandparent claim
Swiss citizenship by descent comes from a Swiss parent (Art. 1 BüG); there is no grandparent route.
Risk of loss at 25 (Art. 7)
A citizen born abroad with another nationality forfeits Swiss citizenship at 25 unless they register or declare to retain it.
A lapsed citizen can't transmit
A parent who already forfeited at 25 cannot pass citizenship to a child.
Reinstatement is possible but costs more
Reacquiring lapsed citizenship carries a higher fee (~CHF 600) than routine consular service.
Handled by SEM via Swiss representations
The State Secretariat for Migration decides, with filings through Swiss missions abroad.
