French Citizenship 2026: Requirements, Routes, Cost, and How to Apply

French citizenship is acquired mainly through naturalization after five years of legal residence, by marriage to a French citizen, or by descent. Since January 1, 2026, applicants must prove B2-level French and pass a civic exam. France allows dual citizenship, and a French passport gives visa-free access to 185 destinations as of 2026.

Why Pursue French Citizenship?

French citizenship confers full EU citizenship, one of the world's strongest passports, and permanent, unrevocable status for those who acquire it by residence. It is the end point of a residence journey, not a shortcut.

France is the EU's second-largest economy and a central player in European politics, so its citizenship carries real weight. A French passport provides visa-free or visa-on-arrival access to 185 destinations as of 2026, ranking among the strongest in the world on the Henley Passport Index. Beyond travel, citizenship grants the right to live, work, study, and retire anywhere in the 27 EU member states, full voting rights, consular protection abroad, and access to France's public healthcare and education systems on the same footing as any other citizen. Unlike a residence permit, citizenship is permanent and generally cannot be lost once acquired.

What Are the Main Routes to French Citizenship?

There are three principal routes: naturalization after five years of legal residence, declaration by marriage to a French citizen, and citizenship by descent through a French parent. A handful of narrower routes exist for children born in France, adoptees, and legionnaires.

The table below compares the main routes at a glance. Each is detailed in the sections that follow.

How Do You Get French Citizenship by Naturalization?

Naturalization by decree is the main route: it requires at least five years of continuous legal residence in France, B2-level French, a passing score on the new civic exam, stable income, and a clean record. It is discretionary, so meeting the criteria does not guarantee approval.

The core conditions for adults over 18 are:

• Residence. Five years of continuous legal residence in France on a valid permit, reduced to two years for graduates of a French higher-education institution.
• Language. B2-level French in speaking and writing, proven by a recognized test (such as TCF or TEF) or an equivalent French diploma. This rose from B1 on January 1, 2026.
• Civic exam. A 40-question multiple-choice exam on French history, values, and society, requiring at least 32 correct answers, introduced for naturalization by decree in 2026.
• Integration and values. Demonstrated assimilation into the French community and adherence to Republican values, assessed at interview.
• Resources. Stable and sufficient income to support the household.
• Good character. No criminal conviction carrying a sentence of six months or more, and no conduct against France's interests.

Certain applicants can be exempt from the residence period, including recognized refugees, those who have served in the French military, and people who have performed exceptional services for France. Naturalization is granted by decree published in the Journal Officiel, and the file typically takes 18 to 24 months to decide. As of 2026, prefectures apply the income and integration criteria more strictly than in previous years.

Can You Get French Citizenship Through Marriage?

Yes. A non-French spouse can acquire citizenship by declaration after four years of marriage to a French citizen, extended to five years if the couple has not lived in France for at least three years of the marriage.

The marriage must be genuine and the French spouse must have kept French nationality throughout. Since 2026, marriage-based declarations also require B2-level French, matching the naturalization standard. Applicants living in France file with the judicial tribunal, while those abroad apply through a French consulate. Spouses applying by declaration are assessed on Republican values through an oral evaluation rather than the written civic exam used for naturalization by decree.

How Does French Citizenship by Descent and Birth Work?

French citizenship passes by descent to children with at least one French parent, provided the family kept meaningful ties to France. Birth on French soil does not by itself grant citizenship, but children born in France to foreign parents can acquire it in their teens under residence conditions.

Citizenship by descent is generally available where a parent is French, though eligibility can weaken when the French parent has lived abroad for a very long period and ties to France have lapsed. For children born in France to foreign parents, the main paths are: those aged 13 to 16 who have lived in France since age 8 (with parental request), and those aged 16 to 18 who have lived in France since age 11, with citizenship acquired automatically at 18 under residence conditions. France's 2024 immigration law tightened these birthright rules, so families should confirm current conditions before relying on them.

Is There French Citizenship by Investment?

No. France has no citizenship-by-investment program and no Golden Visa. Investors instead use the Talent Passport, a multi-year residence permit that, like any residence route, can lead to naturalization after five years.

The Talent Passport covers investors, company founders, and highly skilled professionals, is valid up to four years, renewable, and includes family members. Founders in technology can also use the French Tech Visa. Neither buys citizenship: they establish residence, and the standard naturalization conditions (five years, B2 French, civic exam, integration) still apply. Anyone told they can purchase a French passport directly is being misled.

The Golden Harbors 5-Year Naturalization Readiness Framework

Most naturalization refusals and delays trace back to gaps that were fixable years earlier. Golden Harbors uses a five-point readiness framework to pressure-test a file long before it reaches the prefecture.

What Is the French Citizenship Application Process?

The process runs in five stages: confirm eligibility, assemble the dossier, file online through the ANEF portal, attend the prefecture interview, and, if approved, attend the citizenship ceremony. The whole file typically takes 18 to 24 months.

The stages in practice are:

1. Confirm eligibility. Check residence, language, civic-exam, income, and character conditions against your route.
2. Gather documents. Identity and nationality proof, residence evidence, translated birth and marriage certificates, proof of income and tax compliance, the B2 language certificate, the civic-exam certificate, and criminal-record documents.
3. File the application. Naturalization files are submitted through the national ANEF online portal and routed to your prefecture.
4. Interview. An agent assesses your integration, language, knowledge of Republican values, and motivations.
5. Decision and ceremony. On approval, the decree is published in the Journal Officiel and you attend a ceremony, sign the charter of rights and duties, and can then apply for a French ID card and passport.

The naturalization tax stamp is EUR 255 as of May 1, 2026. A French passport is usually issued within a few weeks of the ceremony.

How Do Americans Get French Citizenship?

US citizens follow the standard naturalization route: five years of legal residence in France, B2 French, the civic exam, stable income, and integration. France permits dual citizenship, so Americans keep their US nationality.

The path starts with a long-stay visa converted to a residence permit, chosen from work, study, family, or financially independent categories. After five continuous years (two if you graduated from a French institution), you file for naturalization. The one point Americans should plan for early is tax: the United States taxes its citizens on worldwide income regardless of residence, so the France-US tax treaty and US filing obligations should be coordinated alongside the immigration timeline, not after citizenship is granted.

Sergey Voinich, Founder and Managing Partner at Golden Harbors, notes: "The single biggest change we prepare clients for now is the jump to B2. People who coasted on conversational French under the old B1 standard are getting caught out. We tell clients to treat the language certificate as a two-year project, not a final-year formality."

How Golden Harbors Helps

Golden Harbors advisors guide entrepreneurs, families, and long-term residents through the full arc from first French residence permit to naturalization. We map the five-year timeline, flag where the 2026 B2 and civic-exam rules reshape preparation, and keep the residence clock, income profile, and document set aligned so the file holds up under stricter prefecture review.

We do not provide tax advice, but for US and other globally taxed clients we make sure the immigration plan is built with the cross-border tax picture in view from the start. Whether you are still choosing a French residence permit or already counting down to eligibility, we run the mandate at the scope you need.

Frequently Asked Questions About French Citizenship

How Hard Is It to Get French Citizenship?

It is achievable but demanding. Naturalization requires five years of legal residence, B2-level French since 2026, a passing civic-exam score, stable income, and a clean record, and the decision is discretionary. The main difficulties are reaching B2 in all four language skills and assembling a complete, well-documented file. Most applicants who prepare early and meet the conditions succeed.

What Is the Easiest Way to Get French Citizenship?

Descent is usually the most direct route for those with a French parent, since it is not test-based. Marriage to a French citizen is another relatively streamlined path after four years. Graduates of French higher-education institutions benefit from a reduced two-year residence requirement for naturalization. The best route depends entirely on your ties to France.

How Long Does It Take to Get French Citizenship?

A naturalization file typically takes 18 to 24 months from submission to decision as of 2026. Timelines depend on the completeness of the dossier, the applicant's circumstances, and the prefecture's workload. Marriage-based declarations follow a similar timeframe. Delays are common, so applicants should plan for a lengthy process rather than a quick turnaround.

What Level of French Do You Need for Citizenship?

Since January 1, 2026, the required level is B2 on the CEFR scale, in both speaking and writing, up from the previous B1. B2 means understanding complex texts and expressing yourself clearly and spontaneously. Proof comes from a recognized test such as the TCF or TEF taken within the last two years, or an equivalent French diploma. The B2 rule applies to both naturalization and marriage declarations.

What Is the New French Civic Exam?

The civic exam is a 40-question multiple-choice test on French history, values, culture, and civic responsibilities, introduced for naturalization by decree on January 1, 2026. Candidates must score at least 32 out of 40 to pass, and the certificate is a mandatory part of the file. Applicants by marriage declaration are assessed on Republican values orally rather than through this written exam.

Can You Get French Citizenship in 3 Years?

In limited cases. Members of the French Foreign Legion can request naturalization after three years of service, though in practice approval often takes longer. Separately, graduates of a French higher-education institution can apply after two years of residence. There is no general three-year route for standard applicants, who need five years of residence.

Can You Buy French Citizenship?

No. France has no citizenship-by-investment program and no Golden Visa. Investors can obtain residence through the Talent Passport, which can lead to naturalization after five years under the standard conditions, but citizenship itself cannot be purchased. It must be earned through naturalization, marriage, or descent following the legal requirements.

Does France Allow Dual Citizenship?

Yes. France has permitted multiple nationality since 1973, so acquiring French citizenship does not require renouncing your existing nationality, and holding another passport does not affect your French status. This makes France attractive to Americans, Britons, and others who want to keep their original citizenship. Your other country's rules on dual nationality still apply separately.

Can You Lose French Citizenship?

It is possible but rare. Citizenship acquired by fraud or false declaration can be revoked, generally within a set period after naturalization. Revocation can also apply for acts seriously harmful to France's national interests, such as terrorism. Citizenship acquired by birth or descent is far harder to remove, and permanent, lawfully acquired citizenship is not lost through ordinary time spent abroad.

How Much Does French Citizenship Cost?

The main official cost is the naturalization tax stamp, set at EUR 255 as of May 1, 2026. Beyond that, applicants typically pay for recognized language testing, certified translations of civil documents, and the civic exam. Costs vary by personal situation and whether professional guidance is used. There is no large investment requirement, because France has no citizenship-by-investment route.

What Is the Easiest EU Country to Get Dual Citizenship as an American?

It depends on ancestry and residence. Ireland and Italy offer descent-based routes for those with qualifying ancestry, often without living there. Portugal allows naturalization after five years of legal residence. Spain requires ten years for most nationals, though it has a route for people of Sephardic Jewish heritage. Note that Spain abolished its Golden Visa in April 2025, and Portugal's Golden Visa now runs through qualifying funds from EUR 500,000.
