Dual citizenship in France Application process & benefits

France is one of the most sought-after countries for foreign nationals aiming to secure dual citizenship, with dual nationals accounting for 5% of the country’s population. With its rich culture, thriving economy, high standard of living, and strong global influence, it is no surprise that France is considered an attractive option for individuals seeking greater personal and professional opportunities.

Since 1973, France has recognised dual citizenship; however, certain exceptions may hinder the application process and force an applicant to renounce their previous nationality.

When can dual nationality be granted in France?

Dual nationality in France can be granted through several pathways, depending on an applicant’s eligibility:

By birth

Dual nationality may automatically apply to children born in France to parents of foreign nationality under specific conditions. Known as jus soli (“right of soil”), new French nationality laws have recently been restricted; nationality is not automatically granted, and French-born children must apply for citizenship between the ages of 16 and 18.

Also, if at least one parent was born in France, the child is often eligible for French citizenship. This is under jus sanguinis (“right of blood”), where there is a strong connection for citizenship. Children born abroad to a French parent may also claim French citizenship by descent.

While a child is under the legal age

A child under 18 may acquire French nationality if their parent applies for citizenship and their application is accepted. If the parent applies for citizenship in France by decree (naturalisation) or declaration (marriage), the child’s name may be stated on the application, leading to French citizenship and dual nationality.

Children with parents that have different nationalities may also obtain triple nationality, as long as each country allows dual citizenship.

By naturalisation

This is one of the most common pathways for foreign nationals seeking French citizenship. Naturalisation generally requires an applicant to have legally resided in France for at least five consecutive years (or two years under certain conditions, such as completing higher education in France).

Under Articles 21-15 to 21-27 of the French civil code, foreign nationals applying for French citizenship by naturalisation must prove proficiency in the French language at a B1 level, have a valid residence permit (if they are not from an EU member state), and knowledge of French history and culture.

By declaration (marriage or descent)

Foreign nationals married to a French citizen can apply for French citizenship after at least four years of marriage, provided the couple still resides together and the French partner retains their citizenship. Similarly, applicants with French family ties may claim citizenship through a declaration.

What are the advantages of obtaining dual citizenship in France?

Securing dual citizenship in France offers numerous benefits, both personal and professional.

These advantages extend beyond the borders of France, especially when paired with citizenship in countries such as the United Kingdom (UK) or the United States (US):

  • Freedom of movement: French citizenship grants unrestricted access to all European Union (EU) member states. This privilege significantly enhances opportunities for work, travel, and residence across Europe, particularly for US and UK business owners.
  • Enhanced career prospects: France is a global hub for industries such as fashion, technology, and finance. Dual citizenship allows easier access to the French job market while benefiting from EU employment rights.
  • Access to public services: Dual citizens can enjoy France’s exceptional healthcare system, world-class education, and robust social security benefits.
  • Cultural immersion: France’s dual citizens can participate more fully in the country’s political and cultural life, including voting rights and eligibility for public office.
  • Global mobility: When paired with citizenship in the US, UK, or another country with a powerful passport, dual nationality expands global travel options without the need for visas.

Are there any disadvantages to gaining dual nationality in France?

While there are many benefits to living, working and gaining citizenship in France, there are potential challenges that may arise with holding dual nationality. Dual citizens may face complex tax obligations, especially when the other citizenship is from a country like the US, which taxes based on worldwide income. French tax regulations should also be carefully navigated to avoid unexpected liabilities.

In addition, dual citizens must comply with the laws of both nations, which can often be conflicting and create future complications.

What is the application process for becoming a French dual citizen?

Firstly, it’s important to assess your eligibility criteria and ensure that your application meets all requirements depending on the pathway chosen. Next, ensure that your country of origin accepts dual nationality, which can be done with your country’s embassy or consulate. Though many countries allow you to be a dual citizen with France, including the United Kingdom, certain ones do not (for example, the Netherlands).

The application process for French citizenship typically costs €55, and includes the following:

  1. Preparation of application: Gather the necessary documentation, including identity proofs, proof of residence, and evidence of integration into French society. You must also demonstrate proficiency in the French language through an approved test, such as the Test of Knowledge (TCF) or DELF Diploma of French Language (DELF), at an intermediate B1 level.
  2. Submitting the application: Applications are typically submitted to the relevant local authority or the French consulate in your country of residence.
  3. Background checks and interviews: French authorities conduct background checks and may require an in-person interview to assess your integration into French society and knowledge of French culture and values.
  4. Final decision: Once all steps are completed, you will receive a decision on your application. If your French citizenship application has been accepted, you will be invited to a citizenship ceremony. This marks your acceptance into the country as a citizen, where you will take an oath of allegiance to France.

Given the complexity of this process and potential pitfalls, professional assistance from Giambrone & Partners can significantly increase the likelihood of success.
