What is the Eligibility Criteria to Apply for French Citizenship?
France is an extremely popular European destination for non-EU nationals seeking citizenship. There are several pathways to becoming a French citizen, which are governed by the Civil Code (Code Civil des Français, commonly known as the Napoleonic Code).
In addition to the required documents for French citizenship, as listed below, applicants must meet specific criteria to be considered. Through the naturalisation route, foreign nationals must have lived in France uninterrupted for five years.
By marriage, foreign nationals must have been married to a French spouse for at least four years before applying for citizenship, as well as living in France for at least three years.
The core eligibility criteria for French citizenship include:
- A clean criminal record
- A sufficient and stable income
- Strong connection to France (Jus Sanguinis or Jus Soli)
- Knowledge of the French language

Understand the Required Documents for French Citizenship
To apply for French citizenship, you will need to compile a dossier of documents to support your application to be submitted together with the application form. The required documents for French citizenship vary depending on the pathway chosen; however, they generally include:
- Proof of Identity
- Proof of Residence
- Proficiency in the French Language Certificate
- A Clean Criminal Record (Casier Judiciaire)
- Two Signed Copies of the Application Form
- Two Recent Passport Photos
Along with a fee (approximately €55, payable with fiscal tax stamps), the application can often be submitted online or at your local préfecture.

Are There Any Additional Documents for Citizenship?
Certain supporting documents may be required depending on the particular route to citizenship:
By Naturalisation
After five years of permanent residency in France, foreign nationals may apply for citizenship by naturalisation. Together with the core documents, you must submit a copy of your French residence permit, proof of income and tax payments to prove financial stability, and evidence of integration.
By Descent or Birth
As France has birthright citizenship, children with at least one French parent will automatically receive citizenship, provided the parent has ties to the country. Due to your ancestry, you may be eligible to apply for a Certificate of French Nationality (Certificat de Nationalité Française or CNF), which confirms your citizenship. To obtain this, you will need a valid passport, proof of address, your birth certificate, and proof of your parents’ nationality.
By Marriage
In addition to the core documents, you and your French spouse will need to provide proof of your legitimate marriage, along with additional documentation. By the marriage pathway, you must submit a copy of your marriage certificate (if married abroad, you must first register your marriage in the French civil registry), and proof of your spouse’s French nationality (such as a French passport or ID card).
If applicable, you must also provide proof of dissolution of previous marriages, through a divorce decree (Jugement de divorce), as well as evidence of cohabitation for at least three years through joint bank statements or utility bills.
How Can You Prove Integration into French Society for Citizenship?
Under the “Controlling Immigration While Improving Integration” law, enacted by France in 2024, stricter restrictions have been imposed on citizenship applications. Through continuous residency and integration into the community, citizenship applicants must prove their commitment to France. Documents to demonstrate this may include a marriage certificate to a French spouse, birth certificates of any French children, library cards, volunteering evidence, and a clean criminal record.
During the citizenship interview, after your application is submitted, you may be assessed on your knowledge of French culture, history, laws, and values. The “Livret du Citoyen” is a helpful document to revise, which summarises these key aspects and helps prepare you for the interview.
French Language Proficiency
New French law reforms have significantly impacted the language requirements. Now, citizenship applicants must demonstrate proficiency in French at a level B1 consisting of listening, reading, writing, and oral components. This requirement level has altered several times.
Your DELF (Diplôme d’études en langue française) certificate should be submitted along with the rest of the required documents for French citizenship.
Translating French Documents for Citizenship Applications
As you prepare your citizenship application, all documents not originally in French must be officially translated by a sworn translator (traducteur assermenté). This ensures comprehensive translations and all details to strengthen your citizenship claim. Documents that are not translated or have details missing will not be accepted.
The required documents for French citizenship, including a criminal record certificate, must also be legally compliant. If your home country is a part of the Hague Convention (such as the United Kingdom), documents must have an apostille stamp, like birth or marriage certificates. This certifies the authenticity of foreign documents and legalises them in France.
Missing or incorrect translation is a common reason for citizenship application delays or refusals. This step should not be overlooked, it should be prioritised for a better chance of success.
At Giambrone & Partners, our French immigration lawyers are available to assess and help gather required documentation during the citizenship application. We will assist in avoiding these issues, and ensure every aspect of your application is legal and meets the eligibility criteria.
