Frequently Asked Questions about French Naturalization

What is a naturalization decree?

A naturalization decree is an official act published in the Official Journal of the French Republic (JORF) that grants French nationality to a foreign person. This decree is signed by the Prime Minister and marks the completion of the naturalization process.

Where can I find my prefectoral number?

The prefectoral number can be found on the receipt of your naturalization application issued by the prefecture. It follows the format YYYYX followed by 6 digits (example: 2026X 045678). The 'X' may be replaced by another letter depending on your prefecture.

How long after submitting my application is the decree published?

The average time between submitting your application and the publication of the decree is 12 to 18 months. This delay may vary depending on the complexity of your case and the workload of the prefectural services. Publication in the Official Journal typically occurs a few weeks after the decree is signed.
