French Dual Citizenship in the U.S. — 2026 Guide

France permits dual nationality without restriction, and a child born in the United States to a French parent is French from birth by descent. Nothing has to be requested for that to be true — but nothing can be proved either until the birth is transcribed into the French civil register.

Quick facts

Where the family link goes back further, or where records are incomplete, the instrument that settles the question is the certificate of French nationality, applied for through the consulate and decided in France.

Routes and what they need

Acquiring U.S. citizenship has no effect on French nationality, and there is no notification requirement in either direction.

How to proceed

1. Establish how the French parent holds nationality and whether their own birth is registered in France.
2. Order the U.S. birth certificate, apostille it and have it translated by an accredited translator.
3. File the transcription with the consulate covering the place of birth.
4. Once the French record exists, apply for the passport and the identity card.
5. Where the chain is older or documents are missing, apply for the certificate of nationality through the consulate.
6. Register on the consular list of French nationals abroad to simplify everything afterwards.

Required documents

• U.S. birth certificate, apostilled and translated.
• French parent’s full birth record, recently issued.
• French parent’s passport or identity card.
• Parents’ marriage record, or the acknowledgment of paternity for births outside marriage.
• Documents linking each generation where a certificate of nationality is sought.
• Proof of address in the consular district.

Where to apply

Transcription goes to the consulate covering the place of birth; nationality certificates are filed through the consulate and decided in France.

Additional notes

Being French and proving it are different

Nationality by descent exists from birth, but without a transcribed record no French administration can act on it. The paperwork is what makes the status usable.

Names

French rules on family names are strict, and a declaration of name choice may be needed at transcription. Resolving it then is far easier than afterwards.

Certificates of nationality take time

These files are decided in France and are measured in months. Start before a deadline exists rather than after.

Voting from abroad

Registration on the consular list is what allows French nationals to vote from the United States, and it is separate from civil status.
