Finnish citizenship by descent
Finland passes citizenship through a parent only — there is no grandparent route — and citizens born abroad can lose it at 22 without a connection to Finland. 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 Finland citizenship specialist in 30 minutes.
🇫🇮 From a Finnish parent
Finland passes citizenship through a parent — confirm your status, and mind the age-22 retention rule.
Eligibility

A grandparent does NOT confer citizenship (only a residence permit).
Born abroad? You can lose citizenship at 22 without a 'sufficient connection.'

Why Finland
What makes Finland different
Parent route only — no grandparent claim
Finnish citizenship by descent comes from a Finnish parent; a grandparent confers no citizenship, at most a residence basis.
Citizenship from birth (§9)
A child of a Finnish parent is Finnish from birth, confirmed by a determination of status.
Risk of loss at 22 (§34)
Citizens born abroad can lose citizenship at 22 without a 'sufficient connection' to Finland.
Retention is a deadline, not a fee
Filing a retention declaration between ages 18 and 22 preserves citizenship for those at risk.
Often fast
A determination of citizenship status is free and can resolve in weeks to a few months.
