A complete guide to the different paths to French citizenship.
Applying to be a French citizen can be a challenging process. This is mainly due to the different pathways to citizenship available, the applicant's specific requirements and new immigration laws, which are subject to change at any time. Most recently, new immigration laws in France came into effect in 2024, limiting renewals of temporary residency permits and raising the required level of French language proficiency to B1.
This guide will summarise all the key information in the different paths to French citizenship and highlight the importance of instructing French immigration lawyers (Avocats).

Applying for French citizenship by marriage: Process and benefits
Under the French Civil Code (Code Civil), foreign nationals can apply to become French citizens if they have a French spouse. To qualify for French citizenship through marriage, applicants must be married for at least four years to a French spouse (with documents to prove nationality). The couple must live together as a married couple and the marriage must be registered in the French civil registry.
After being married to a French spouse for four years or more, foreign nationals can apply for French citizenship at their local préfecture. The application fee is €55, which must be paid using fiscal tax stamps (timbres fiscaux), and submitted alongside a comprehensive dossier of the required documentation to support the application.
French citizenship applications by marriage must include proof of address and cohabitation, the marriage certificate and evidence of the spouse’s French nationality (such as their passport).

Dual citizenship in France
France is one of the most sought-after countries for foreign nationals aiming to secure dual citizenship, with dual nationals accounting for 5% of the country’s population.
Securing dual citizenship in France offers numerous benefits, including permitting freedom of movement across all European Union (EU) member states, as well as access to French public services. This is particularly beneficial for applicants who have lived in the country for five years or have French ancestry.
When applying for French dual citizenship, ensure the application meets all requirements, depending on the pathway chosen. Next, ensure that your country of origin accepts dual nationality, your country’s embassy or consulate can provide this information. Though many countries allow you to be a dual citizen with France, including the United Kingdom, there are those that do not, for example, the Netherlands.

What is the process to apply for French citizenship by naturalisation?
Naturalisation or residency is a very common route to French citizenship. Eligibility for French citizenship by naturalisation is contingent on several factors; primarily, applicants must have continuously lived in the country for at least five years.
Applicants must also be able to prove their integration into French society through understanding French history and culture. They are also required to have at least a B1 level in French, as defined by the Common European Framework of Reference for Languages (CEFR).
After gathering the necessary documentation to support naturalisation, which includes a copy of your French residence permit and proof of address, you can submit your citizenship application form (cerfa) at your local préfecture or online via France’s dedicated portal for naturalisation requests along with a €55 application fee.
A critical part of the process is the interview with an official at the préfecture or consulate. During this meeting, you will be asked questions about your personal history, reasons for seeking citizenship, and understanding of French culture and values. If successful, you will be notified of your approval and invited to attend a naturalisation ceremony where you will receive your citizenship certificate.

Applying for French citizenship by descent or by birth
For individuals with a connection to France through birth (jus soli) or descent (jus sanguinis), acquiring French citizenship can offer numerous benefits, such as free travel in the European Union (EU), the right to live and work in the country, and strengthening a familial connection.
France has birthright citizenship, meaning children born there will automatically obtain their parent’s nationality. For example, if a child is born in France and at least one parent holds French nationality, the child is automatically a French citizen.
French citizenship by descent (jus sanguinis or “right of blood”) is determined through a bloodline connection to a French parent or grandparent and their family lineage. This pathway applies regardless of the applicant's birthplace, provided they can demonstrate that their parent or grandparent was a French citizen and had maintained ties with France at the time of the applicant’s birth.
Unlike other pathways, if you are applying for French citizenship by descent, you do not need to demonstrate knowledge of the French language, history, or culture during the application process.
If you meet the eligibility criteria for French citizenship, the next step is to apply for a Certificate of French Nationality (Certificat de Nationalité Française or CNF). This document serves as proof of your citizenship. Gather all documents, including the €55 application fee, and submit the application to the Ministry of Justice (Ministère de la Justice).
