How do New Law Reforms Impact on the French Citizenship Application Process?
France divides citizenship applications into jus soli (right of the soil) and jus sanguinis (right of blood). In January 2024, France enacted the "Controlling Immigration While Improving Integration" law, marking a pivotal shift in its approach to immigration and integration. This new law reform aims to control foreign workers and tighten restrictions on French citizenship applications. Legislation focused on three primary objectives:
- Integration through employment: Addresses economic needs while allowing undocumented workers to legalise their status through employment.
- Commitment to Republican principles: Foreign nationals with a valid residence permit will now be required to sign a contract affirming their commitment to upholding the principles of the French Republic.
- Knowledge of French language: Tightens language proficiency requirements for residency and citizenship applications.
The 2024 reforms have introduced several changes directly affecting the French citizenship application procedure. One of the most significant shifts is the increase in language proficiency requirements, raised from B1 to B2.
French citizenship applicants must take the TCF IRN language exam, which consists of listening and reading comprehension as well as written and oral expression in French. The language test certificate must be submitted alongside proof of knowledge of French culture and history, as well as sufficient integration into society.
In addition, law reforms have restricted French citizenship by birth, and those born in France to foreign parents will no longer be automatically granted French nationality.
Which French Citizenship Laws Should You Be Aware Of?
Governed by the Civil Code (Code Civil des Français or The Napoleonic Code), France’s Nationality law regulates citizenship and upholds legislation and eligibility criteria.
For foreign nationals applying for French citizenship by naturalisation, the key legal provisions of the French Civil Code include:
- Articles 21-15: Requires applicants to demonstrate a sufficient degree of integration into French society. Examples include a diploma from a French higher education institution, and active participation into French society.
- Articles 21-16: Citizenship applicants must demonstrate a B2 level of French language proficiency in both spoken and written communication (as of 2024).
- Articles 21-24: Details minimum residency required for citizenship, which is generally five consecutive years. This period can be reduced to two years for those who have completed higher education in France or made significant contributions through research, economic investment, or artistic achievements.
Residency must be lawful and uninterrupted, meaning absences from France can impact eligibility.
These bills have come under scrutiny, with calls for a new French immigration law in 2025. Legislative changes can be difficult to navigate, particularly for foreign nationals unsure about French laws.

Understanding French Citizenship by Marriage Laws
French nationality law permits foreign nationals married to French citizens to apply for citizenship through a declaration process governed by the French Civil Code (Code Civil):
- Article 21-2: Foreign nationals who marry a French citizen are entitled to French nationality through a declaration after a specified period (four years) and must demonstrate a “community of life” with their partner.
- Article 26-1: All declarations of nationality must be registered by the relevant authority. Citizenship by marriage to a French spouse must be declared in the Conseil d’Etat.
These articles outline the circumstances that must be upheld by foreign nationals looking to acquire citizenship. You must have been married to your French spouse for at least four years at the time of application. The couple must also have lived together continuously since the marriage (referred to as “vie commune”), and the marriage must be legally registered in the French civil registry.
French law also protects citizenship in the case of divorce or separation. If you submit your application while still legally married and cohabiting, and your application is approved, you retain your French citizenship even if you later divorce.
Your citizenship application and separation dates will be considered. If less than a year has passed, the French government has the right to revoke or re-evaluate your citizenship.
