Complete guide: prefecture Yvelines naturalization and administrative procedures
Your journey towards French nationality will mainly depend on your family situation and your length of residence. There are four main pathways, each with its own conditions.

Understanding the procedures via decree and declaration
The decree procedure applies to individuals over 18 years old with five years of continuous residence in France. This is the most common route for naturalization applications.
The declaration by marriage applies after four years of union with a French spouse and three years of presence in the territory. Since February 2023, this procedure requires a physical appointment.
Eligibility criteria and specific conditions
For ancestors over 65 years, you must justify 25 years of residence and have a descendant of French nationality. The declaration by family link offers another possibility.
If you have a brother or sister who is French and born in France, and you completed your compulsory education here, this route applies to you. Each brother-sister situation is studied individually.
Clearly identify your profile before starting the procedures. The administration offers support to determine the best nationality pathway according to your background.
The essential documents and supporting materials
Your file relies on a precise list of forms and supporting documents to provide. Rigorous preparation is key to avoid any rejection.
Start by downloading the correct application form. The choice depends on your situation.
List of documents to provide for the file
The civil status documents form the foundation of your file. They prove your identity and family background.
Your list of documents must also include additional supporting materials.
- Valid residence permit and proof of residence.
- Employment certificates or proof of stable income.
- Degrees and certificates of French language proficiency.
An incomplete file will be rejected. Organize your documents in the indicated order.
Translation, apostille, and legalization requirements
Documents in a foreign language require an official translation by a certified expert. Always provide the original and its translation.
For authentication, two procedures exist.

Do not forget the mandatory electronic stamp since 2019 for any application for access to nationality.
