French Nationality B2 Requirements (2026 Rules)
What the B2 French requirement means for naturalisation in 2026, which certificates are commonly accepted, and how to prepare without failing the language step.
Quick Answer
Under the tightened 2026 naturalisation language expectations, candidates should plan for solid B2 French with an accepted certificate (commonly DELF B2 or an accepted TCF nationality/IRN result). Do not wait until the prefecture appointment to discover your level is still B1.
What B2 means in practice
B2 means you can argue a point, follow complex speech, and write structured texts on familiar and abstract topics. Memorized interview scripts are not enough if the examiner pushes follow-up questions.
Certificate strategy for 2026
DELF B2 remains the cleanest long-term proof because it never expires. TCF nationality/IRN routes can work if valid at submission time. Verify the prefecture’s accepted list for your department.
- Target real B2 production, not borderline B1+.
- Book the exam early enough for results to arrive.
- Keep digital and paper copies of certificates.
- Continue French practice after the exam until the interview.
Study focus that moves the needle
Prioritize speaking spontaneity, listening to authentic French media, and writing opinion texts with clear structure. Grammar study should fix recurring errors, not replace production practice.
Practice next
Use a nationality-focused B2 plan with speaking and writing practice before you book DELF or TCF IRN.

Frequently asked questions
Is B1 still enough for French nationality?
Plan for B2 under the 2026 language tightening. Relying on older B1 assumptions is a common reason files stall. Confirm current prefecture guidance for your case.
Is DELF B2 mandatory?
Not always mandatory as the only path, but it is one of the clearest accepted proofs. Other accepted certificates may exist; the level target is B2.
How long before the prefecture should I take the exam?
Early enough that results arrive before submission, with buffer for a retake. For expiring certificates, stay inside the validity window through the decision period when possible.
