France dual citizenship rules

Who Can Hold French Dual Citizenship?

France permits dual citizenship for people who acquire French nationality through birth, marriage, or naturalization. However, France doesn't require you to renounce your original citizenship when you become French. This means dual citizenship happens automatically in many cases—you don't need to apply for it specifically.

How You Can Acquire French Nationality

By birth: If you're born in France to at least one French parent, you're automatically French. If both parents are foreign but you're born in France, you may become French at age 18 if you've lived there for at least five years.

By marriage: After marrying a French citizen, you can apply for French nationality. You'll typically need to be married for a certain period and meet residency requirements.

By naturalization: If you've lived in France long enough and meet language and integration requirements, you can apply to become a French citizen.

By descent: If your parents or grandparents are French, you may be eligible even if you were born abroad.

Important Things to Know

• France doesn't ask you to drop your other nationality. When you gain French citizenship, the French government won't require proof that you've given up your original citizenship.
• Your other country might care. Some countries do require you to renounce other nationalities when you become their citizens. Check your original country's rules.
• Rights and responsibilities apply. As a French dual citizen, you have voting rights and obligations in France. You may also retain duties in your original country.

What You Need to Do

Start by checking the official French government immigration website (France-Visas or your nearest French embassy) for current requirements. Each path to citizenship has different documents, timelines, and conditions. You'll need to provide proof of identity, residence history, and often language proficiency.

Requirements and processes change, so confirm everything directly with official sources before applying. Your situation is unique—an immigration lawyer familiar with both France and your home country can give personalized guidance.
