French Naturalization by Decree
Prepare proofs of legal residence, integration, and financial stability. Naturalization by decree applications are evaluated on your individual circumstances.
Check residency duration
The standard rule requires five years of continuous regular residency in France prior to applying. The Civil Code provides reductions and exemptions in specific cases. Verify legal stay and integration criteria.
Prepare French language and civic test proof
Since January 1, 2026, level B2 (oral and written) and passing the civic knowledge exam are standard requirements. Consult recognized certificates and applicable exemptions.
Gather supporting documents for your situation
Prepare identity, civil status, residence, and income documents. For foreign documents, check sworn translation, apostille, or legalization requirements.
Submit application and monitor status
In France, apply online according to Service Public guidelines. The tax stamp is €255. The prefecture examines your file and may invite you for an assimilation interview.
