French reintegration is for someone who personally held French nationality and later lost it. The reason for the loss determines whether the person can use a declaration or must apply for a discretionary decree.

Summary

Reintegration is for a person who previously was French and later lost French nationality. The first task is to prove the former nationality and the legal event that ended it. A family story that an ancestor was French is not enough; if the applicant personally never held French nationality, descent or naturalization must be assessed instead.

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.

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 discretionary.

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.

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 civil-status 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 civil-status and criminal records, with the required legalization/apostille and approved translations.
  8. File with the competent court or consulate for a declaration, or through the official naturalization/reintegration application process for a decree.
