Frequently Asked Questions (Updated 2025)
Can I keep my original citizenship when becoming French?
Yes! France allows dual citizenship, so you can keep your original nationality. However, check if your home country allows dual citizenship as some countries require you to renounce their citizenship.
What level of French do I need for naturalization in 2025?
Currently B1 level (oral and written) is required until January 2026. After that, it increases to B2 due to the 2024 immigration law. B1 is intermediate level - you must pass TCF IRN, TEF IRN, or equivalent tests.
How long does French naturalization take in 2025?
Processing times vary greatly by prefecture - from 12 months (Paris) to 4+ years (smaller prefectures). The legal requirement is 18 months maximum, but many exceed this. The 5-year residence requirement is just the beginning.
Should I apply now before the B2 requirement takes effect?
Yes, if you're eligible now with B1 level French, it's advisable to apply before January 2026 when the requirement increases to B2. B2 is significantly more challenging than B1.
What happens if my naturalization application is rejected?
You can appeal within 2 months to the Minister responsible for naturalization. If that fails, you can make a contentious appeal to the administrative court. Having legal assistance is recommended.
How difficult is the French citizenship interview in 2025?
The interview is quite demanding and subjective. You'll be tested on French republican values, history, culture, and your integration into French society. Genuine knowledge of French civic principles is essential.

Tips for Success in French Naturalization (2025)
Master French Early
Start learning French immediately. Aim for B2 level even though B1 is currently required - the requirement is increasing to B2 in January 2026.
Show Deep Integration
Join French associations, volunteer, attend cultural events. Document your integration beyond just language - France values genuine cultural assimilation.
Keep Perfect Records
Document everything: tax returns, residence permits, utility bills, integration activities. French authorities are extremely thorough and detail-oriented.
Learn Republican Values
Study French history, laïcité (secularism), and republican principles deeply. The civic interview tests genuine understanding, not memorization.
Consider Legal Help
For complex cases, previous rejections, or if unsure about requirements, consult an immigration lawyer specializing in French naturalization.
Apply Before 2026
If you meet current B1 requirements, apply immediately. The B2 requirement starting January 2026 will be significantly more challenging.
