DELF for French Citizenship and Residency: A2, B1 and B2 Rules in 2026
Quick Summary: France raised its language bar on 1 January 2026. A multi-year residence card now needs A2, the 10-year resident card needs B1, and naturalization needs B2, alongside a civic knowledge exam. DELF and DALF diplomas are accepted as proof and never expire. TCF and TEF count only in the IRN version. This guide maps each level to each procedure and shows how long the gap takes to close.
