A practical guide to recovering French nationality once you’ve lost it: the two available routes, who qualifies for each, the 2026 language and civic exam rules, and the full process. Brought to you by the immigration team at LegalMova.
If you were once French and lost that nationality, reintegration is the legal process that lets you recover it. It’s a distinct legal mechanism from naturalization: naturalization is for people who have never held French nationality and are acquiring it for the first time, while reintegration is specifically for people re-establishing something they already had.
There are two separate routes into reintegration, and which one applies to you depends entirely on how you lost your French nationality in the first place. Getting this distinction right matters, since the two routes have genuinely different conditions, costs, and timelines.
This is the faster, more accessible route, but it only applies to specific situations defined by law:
If one of these applies to you, the declaration route doesn’t require the 5-year residence test that reintegration by decree does. Instead, the core conditions are that you must have kept or reacquired clear ties to France, whether cultural, professional, economic, or family, and that you’re not currently under an active expulsion order or a French territory ban. If you’re applying while living in France, you also need to be in regular stay, holding a valid provisional document or residence permit.
Because this route is a declaration rather than a discretionary decision, and because the NAT civic exam applies specifically to decree procedures, this route does not require passing that exam. Whether the B2 language requirement applies here the same way it does for the decree route below is worth confirming directly for your specific situation before you plan your file.
This is the general route, used whenever your situation doesn’t fit one of the specific declaration scenarios above. Unlike the declaration route, it’s discretionary: even meeting every formal condition doesn’t guarantee approval.
You must establish that you previously held French nationality. There’s no age limit: reintegration is possible at any age, though applicants under 16 need to be represented by a legal representative, and from age 16 you can apply on your own.
You need to be resident in France at the moment the reintegration decree is signed, meaning France needs to be the center of your material interests (particularly professional) and your family ties. If you live in France but your spouse and children live abroad, this can actually work against your application.
There are exceptions, though. You can be reintegrated while living abroad if you fall into one of these situations: you carry out public or private professional work on behalf of the French state or an organization whose activity holds particular interest for the French economy or culture, you reside in Monaco, you’re completing French national service or are enlisted in a regular French army formation, or you’re a national service volunteer. If one of these applies to you, your spouse and any minor children living with you need to meet the same condition too.
You need a valid residence permit at the time of filing, unless you’re an EEA or Swiss national. You also can’t be under an active expulsion order or territory ban.
Your assimilation into French society is verified through two things: passing the NAT civic exam, and a prefecture interview. This is the same civic exam introduced for naturalization on January 1, 2026: computer-based, 40 questions, 45 minutes, requiring a score of at least 32/40 to pass. You also need to justify a sufficient level of French, under the same B2 standard that applies to standard naturalization since January 1, 2026.
Professional integration matters too: you need stable, sufficient income to support yourself and your household. And you need to be of good conduct, meaning no unsuspended prison sentence of 6 months or more in France, and no conviction for a crime or offense against the fundamental interests of the nation or an act of terrorism, subject to exceptions for rehabilitation.
Reintegration by decree costs €255 (€127.50 in French Guiana), paid via electronic stamp duty, confirmed directly on the official procedure page. If you file from abroad, payment happens at the consulate when you submit your file rather than online.
The core file includes: the completed Cerfa n°12753 form, your stamp duty, a copy of your valid residence permit, an official identity document, two passport photos, civil status and nationality documents, proof of address, proof of income and tax situation, your B2 language proof, your NAT exam success certificate, and, where relevant, documents covering your marital history or any minor children. If you’ve lived in France for less than 10 years, you’ll also need a criminal record extract from your country or countries of residence, or your country of nationality, unless you’re a refugee or stateless person protected by Ofpra.
Foreign civil status documents need a full, original copy in the language of the country of origin, and any document in a foreign language needs a French translation from an accredited translator. Some foreign documents also need legalization or an apostille before they’re accepted.
If approved, the decree takes effect on its signature date, and any unmarried minor children living with you become French too if they’re named in the decree.
A reintegration application can be refused as inadmissible (irrecevable) if the legal conditions simply aren’t met, in which case you can reapply once the issue is resolved, or as not currently appropriate (inopportune), which can mean either an outright refusal or a deferral giving you time to address a specific weakness before reapplying.
If refused, you have 2 months from notification to file a mandatory administrative appeal (recours hiérarchique) to the Minister responsible for naturalizations. If that appeal is rejected, or you hear nothing within 4 months, you then have 2 months to escalate to the Tribunal Administratif de Nantes, which holds specific national jurisdiction over nationality cases.
Even after a decree is granted, it isn’t fully final right away: it can still be withdrawn within 2 years of publication in the Journal Officiel if the administration later finds the conditions weren’t actually met, or within 2 years of discovering fraud, regardless of when that fraud took place.
What’s the difference between reintegration and naturalization? Naturalization is for people acquiring French nationality for the first time. Reintegration is specifically for people who previously held French nationality and are recovering it.
Do I need 5 years of residence to apply for reintegration? Only for reintegration by decree, and even then residence is required at the time of the decree’s signature rather than as a fixed multi-year count, with several exceptions for people living abroad in qualifying situations. Reintegration by declaration doesn’t carry this requirement at all.
Does the NAT civic exam apply to reintegration? Yes, but only for reintegration by decree. The declaration route, covering cases like losing nationality through marriage to a foreigner, doesn’t require it.
Is there an age limit for reintegration? No. Reintegration by decree is possible at any age, with minors under 16 applying through a legal representative.
What if I’ve lived outside France for decades? That alone doesn’t disqualify you from reintegration by decree, but you’ll generally need to establish residence in France by the time the decree is signed, unless you fall into one of the specific exceptions for people working abroad in France’s interest, living in Monaco, or serving in French national service.
Every case is different. Whether your situation fits the faster declaration route or the general decree process, how your prior residence abroad affects your file, and what documentation will actually hold up are exactly the kinds of complexities our team at LegalMova handles every day.
