French Citizenship Reinstatement

France Citizenship
Pathway overview

At a glance

If you personally used to be French and later lost French nationality, you may be able to regain it. You need records proving both the earlier citizenship and how it ended. If only an ancestor was French, consider descent or naturalization instead.

Who can apply
A person who was previously French, not a descendant who was never French
Declaration route
Limited historic loss situations plus continuing ties with France
Decree route
Usually requires living in France, B2 French, the civic exam, and full government approval

Summary

This route is for former French citizens, not descendants who were never French. The cause of loss determines whether the route is a declaration based on continuing French ties or a discretionary decree application centered on present life in France.

Start with your own former French nationality
  1. Prove prior nationality and its loss Establish that you personally were French, and identify the date and legal reason that nationality ended.
  2. Select declaration or decree The reason for loss and your present circumstances determine which reintegration procedure may apply.
  3. Meet that procedure’s conditions Prepare the required French ties or residence, language, civic, and integration evidence for the selected procedure.

First check whether you may still be French. Reintegration generally restores nationality for the future; it is not an ancestry route for someone who personally never held it.

Eligibility

Every reintegration case starts with:

For a declaration, the loss must fit one of the official declaration categories. The applicant must show manifest, personal, and continuing ties with France, which may be cultural, professional, economic, or family-based. If living in France, the applicant must have lawful status. The official procedure also requests criminal-record evidence and documents concerning short Schengen stays where relevant.

For a decree, the applicant can apply at any age, but must ordinarily have the main home in France when the decree is signed. There is no standard five-year wait, yet the administration still reviews professional integration, resources, family center, conduct, assimilation, B2 spoken and written French, and the nationality civic exam. The decision remains a case-by-case decision.

Loss connected to the independence of a former French territory can be unusually complex. Before assuming reintegration is needed, determine whether the applicant actually lost nationality under the transition law or may still be French.

More about this route

France has two different reintegration procedures:

Since 1 January 2026, reintegration by decree normally requires B2 French and a passing nationality civic exam. The civic exam does not apply to reintegration by declaration.

What This Route Allows

Reintegration restores French nationality for the future. It does not normally rewrite every legal event during the years when the applicant was not French.

Eligible unmarried minor children living with the applicant can sometimes benefit from collective effect if they are named and documented in the declaration or decree. Once reintegration is recorded, the person can update French birth, marriage, and other family records and apply for French identity and passport documents.

What This Route Is Not

This is not a descent shortcut for a grandchild or other relative of a former French citizen. The applicant must have been French personally.

It is also not one uniform process. A declaration case should not be presented as decree naturalization, and a decree case cannot ignore current residence in France, B2 French, the civic exam, or professional integration merely because the applicant once held French nationality.

A past passport can be important evidence, but it may not prove the date or legal reason for loss. Conversely, acquiring another citizenship did not always automatically end French nationality. The law in force at the time matters.

Next Steps

  1. Gather the strongest evidence of former French nationality: a certificate of French nationality, nationality decree or declaration, annotated French birth record, old passport or identity card, consular file, or court decision.
  2. Obtain the instrument or foreign-law evidence showing when and why nationality was lost.
  3. Check first whether the person may still be French; request a certificate of French nationality where existing status is uncertain.
  4. Match the loss to the official declaration categories. If it does not fit, assess reintegration by decree.
  5. For declaration, assemble records proving current and continuing cultural, professional, economic, or family links with France.
  6. For decree, confirm that France is the applicant's main home, obtain B2 language evidence, and pass the nationality civic exam.
  7. Collect family-status and criminal records, with the required legalization (official checks confirming a document's origin for use abroad)/apostille (a certificate verifying an official signature or seal for use abroad) and approved translations.
  8. File with the responsible court or consulate for a declaration, or through the official naturalization/reintegration application process for a decree.
