About this procedure

Becoming French through naturalisation is a long, document-heavy process with strict conditions on residence, integration and language. There are different routes, including by decree (residence) and by marriage. The assistant helps you understand which route fits you, the residence and language requirements, how to build a strong dossier and what to expect from the interview and the long processing times.

Documents usually involved

  • Full birth certificate with sworn translation
  • Proof of continuous residence in France
  • Tax notices and proof of stable resources
  • French language certificate at the required level
  • Clean criminal record documents where required

Your done-for-you dossier turns this into a checklist tailored to your exact case.

Frequently asked questions

How many years of residence do I need?

Usually several years of continuous residence for naturalisation by decree, with reductions in some cases, and different rules by marriage. The assistant checks which applies to you.

What French level is required?

A minimum spoken and written level proven by an approved certificate; the required level can change. The assistant tells you how to confirm the current requirement.

How long does it take?

Naturalisation is slow, often well over a year, and varies by préfecture. A complete, well-prepared dossier is the best way to avoid extra delays.
