French sibling declaration

Summary

France has a narrow citizenship declaration for some people born and raised in France whose sibling became French through France's birth-and-residence rules.

This is not a general route for anyone with a French brother or sister. It is tied to being born in France, living there from childhood, and completing compulsory schooling there.

Eligibility

You may be a fit if:

• You were born in France.
• You are at least 18.
• You live in France.
• Your brother or sister became French because they were born and resident in France under the relevant French nationality rules.
• You lived in France from about age 6.
• You completed compulsory schooling in France in an institution under state control.
• You can document the family relationship, residence, schooling, and your sibling's French nationality.

What This Route Allows

If the facts and records fit, this route can support a declaration of French nationality.

It can help some people who grew up in France but did not become French automatically through the ordinary age-18 birth-in-France route.

What This Route Is Not

This is not a sibling sponsorship route. Your sibling's French nationality matters only because it connects to a specific statutory declaration for people born and schooled in France.

It is also not a route for someone born outside France.

Next Steps

1. Confirm how your sibling became French.
2. Gather your birth certificate and proof of your sibling relationship.
3. Gather proof of your residence in France since childhood.
4. Gather school records showing compulsory schooling in France.
5. Gather your sibling's French nationality records.
