Dual citizenship in France: broadly accepted
France receives a rating of 100 out of 100 points for Dual Citizenship Allowed. The assessment is very strong because France generally accepts multiple nationality and does not normally require a person to give up a previous nationality simply because French nationality is acquired.
For migrants, families and people with ties to more than one country, this is a major relocation advantage. France treats multiple nationality as a manageable legal reality rather than a narrow exception, allowing origin ties, family rights, EU rights and long-term integration to coexist more easily.
Dual citizenship is still not automatic. French law is only one side of the analysis. The other country’s law may allow, restrict or end nationality when another citizenship is acquired.
What the measured value means
The measured starting point is a legal category: multiple nationality is generally allowed in France. Nomadino rates countries higher when this position is clear, broad and practically usable.
The assessment looks at whether dual nationality can remain possible through birth, descent, marriage, naturalisation or reacquisition. It also considers whether the rule is publicly explained and whether broad exceptions or loss rules make it hard to use in practice.
France belongs to the top group because it does not broadly prohibit multiple nationality. The practical caution usually lies with the other country, consular duties and the rights or obligations each state continues to claim.
Practical meaning for naturalisation and families
For long-term residents in France, the open approach can make naturalisation easier to consider. If a person may keep their existing nationality, there is less conflict between origin rights, inheritance, family ties, mobility and French integration.
For families, the issue is equally important. Children may hold more than one nationality depending on descent, place of birth and the parents’ legal situation. That can strengthen travel and residence rights, but it can also create passport, military-service or registration duties elsewhere.
French citizenship also carries EU mobility value. Dual nationality can therefore be more than a symbolic status; it can change residence, work and settlement rights across the European Union.
Rules, access and evidence
France separates acquisition of nationality from the question of whether another nationality may remain alongside it. Official French information explains that multiple nationality can be possible.
Naturalisation still requires the normal checks: residence, integration, language, conduct, documents and procedure. Acceptance of multiple nationality does not replace those requirements.
The other country must be checked separately. If the origin state treats acquisition of another citizenship as a loss event, France cannot prevent that. The practical review is always two-sided.
Limits of the assessment
This indicator only rates the general acceptance of multiple nationality. It does not measure how fast naturalisation is, how difficult language evidence is or how hard it is to obtain documents from the origin country.
Tax duties, military obligations, consular protection, naming law and inheritance are not fully captured either. More than one nationality can bring advantages and additional duties.
The high value therefore means that the French legal position is open. It does not mean every application is simple or that the second country is equally open.
What to check before relying on this indicator
Before naturalisation, check whether the existing nationality can be kept and whether the origin country requires permission, notification or a deadline.
Then review French requirements, document collection, translations, residence evidence and family consequences.
For children, spouses and people with several homes, passport use, tax status, military-service issues and consular responsibility should be reviewed separately.
Frequently Asked Questions
Does France allow dual citizenship?
Yes. France generally does not broadly exclude multiple nationality. The other country’s law still needs to be checked.
Does a person naturalising in France have to give up the old passport?
Not as a general French requirement. Whether the previous nationality remains depends on the origin state’s law.
Is dual citizenship the same as easy naturalisation?
No. Naturalisation requirements still apply. Dual citizenship only describes whether more than one nationality can coexist.
What risks should be checked?
Tax, military-service duties, passport use, consular protection, inheritance and loss rules in the other country are the main practical issues.
