How to Apply for French Nationality: Naturalization Guide (2026)

Applying for French nationality by naturalization is a significant commitment that typically requires at least 5 years of continuous residence in France (reduced to 2 years for graduates of French higher education institutions). You must demonstrate sufficient integration: B2-level French, knowledge of French values and history, stable employment, and clean criminal record. The process is long — 12 to 18 months from submission — but grants you full EU citizenship rights.

Practical Tips

Start preparing your dossier 6 months before you plan to submit. Gathering translated and apostilled documents from your home country takes time.

The B2 French language requirement is non-negotiable. Take the TCF or DELF B2 exam well in advance. Some nationalities are exempt if they studied in French.

All foreign documents must be translated by a sworn translator (traducteur assermenté) and apostilled or authenticated by your home country. Budget 50-100 € per document.

Since January 2026, you must pass a formal civic exam (examen civique) — a 40-question digital QCM covering French values, history, institutions, and civic life. You need 80% (32/40) to pass. The questions are published on the Ministry website. The exam is required for naturalization, carte de séjour pluriannuelle, and carte de résident.

Your tax notices (avis d’imposition) for the past 3 years must show consistent income and tax compliance. Gaps or irregularities can delay the process.

Frequently Asked Questions

How long do I need to live in France before applying?
Generally 5 years of continuous, legal residence. This is reduced to 2 years if you completed a degree at a French higher education institution, or waived entirely for spouses of French citizens (after 4 years of marriage).
Can I keep my original nationality?
France allows dual nationality. However, check your home country’s laws — some countries (like Germany or Japan, with exceptions) require you to renounce your original citizenship when acquiring another.
What happens during the prefecture interview?
An officer will assess your French language skills, knowledge of French values (liberté, égalité, fraternité, laïcité), understanding of French history and institutions, and your degree of integration (work, community involvement, etc.).
What if my application is refused?
You can request a review (recours gracieux) within 2 months of the decision, or file an administrative appeal with the tribunal administratif. Common reasons for refusal include insufficient French level, unstable income, or incomplete dossier.
Are there exemptions for older applicants?
Yes. Applicants aged 65 and over are exempt from both the B2 French language requirement and the civic exam (examen civique). This exemption was established by Décret 2025-647.
