How long does it actually take to get French citizenship if I move to Réunion?

The standard timeframe is five years of legal and habitual residence in France (Réunion counts), followed by the naturalization application. Expect the application processing to take 12–24 months in typical cases, so plan on roughly 6–7 years from initial arrival to passport in average scenarios. Some exceptions reduce the residence requirement (see next FAQ).

What are the real costs I should budget for?

Direct state fees are modest (long‑stay visa fees ~€99; titre de séjour production taxes carry fees roughly €200–€300 depending on the card). However, realistic total costs to cover relocation, document collection/apostilles, sworn translations, language testing, and legal or relocation advice commonly fall in the €2,000–€5,000 range — many applicants estimate around €3,000 in out‑of‑pocket costs before indirect costs (lost earnings, travel).

Does France allow dual citizenship if I naturalize through Réunion?

Yes. France recognizes dual (and multiple) citizenship. You should however confirm with your current country of citizenship whether they permit dual nationality, and whether any obligations (military service, exit taxes) apply.

Can I speed up the process by investing in Réunion or buying property?

No. There is no citizenship‑by‑investment or golden‑visa program specific to Réunion. Purchasing property does not shorten the residence requirement — the naturalization route requires genuine, habitual residence and integration regardless of investment level.

Is living in Réunion treated any differently than living in mainland France for naturalization?

Substantively no: residence in Réunion counts the same toward the five‑year requirement and the same language and integration tests apply. Practically, local administrative capacity and appointment availability at the Préfecture can affect scheduling and processing times, so expect local procedural variations but the legal criteria are national.

Réunion (French Overseas Department) Citizenship & Second Passport Guide 2026

Réunion is one of France’s five overseas departments and an EU outermost region in the western Indian Ocean. Legally it is part of France: French law applies, the euro is the currency, and people born there are French citizens. For someone seeking a second passport or EU citizenship, Réunion represents a geographically attractive entry point to French life (tropical climate, lower population density than many European cities) while delivering the full legal and travel benefits of France and the European Union. Importantly, immigration and naturalization rules for Réunion are the same as for metropolitan France — the Prefecture of La Réunion administers residence permits and naturalization applications locally, but the criteria (residence duration, language and integration tests, clean criminal record and stable means) follow national law. The primary route to a French passport via Réunion is ordinary naturalization: move to Réunion on an appropriate French long‑stay visa, register and maintain legal residence, integrate (language and social ties), and apply after the statutory residency period (typically five years). There are also accelerated routes in limited cases: marriage to a French citizen, recognized exceptional services to France, or prior study/long legal residence in France that reduce the residence requirement. Practically speaking, the pathway is not a citizenship-by-investment program — it relies on genuine, habitual residence and integration rather than a single lump‑sum donation or investment. Costs are front-loaded around relocation, visa/residence card fees, document collection, translations and legal assistance; the state’s administrative fees are modest, but professional help and certification can push realistic total costs into a low‑thousands range. Key caveats: Réunion’s remoteness means additional travel time and expense to and from Europe, and certain specialist services and international business networks are smaller than in mainland France. Taxation follows the French system: if you become a French tax resident, you will be subject to French worldwide taxation. Also note that some EU rules are adapted for outermost regions — but citizenship still grants full EU and Schengen travel rights once you hold a French passport. For high‑net‑worth individuals seeking quick citizenship, Réunion/France offers no short cut; the route requires time, documented residence, language competence and demonstrated integration.

Step-by-Step Process

Standard naturalization via five years of legal residence (non‑EU nationals)

Obtain a long‑stay visa (visa de long séjour) for France — worker, student, family or other valid category: Apply at the French consulate in your country with required documents (passport, purpose of stay, proof of solvency, criminal record, medical if required). Wait for visa issuance and travel to Réunion. — 1–3 months (consulate processing varies by country) — €99–€110 (visa fee) + document/legalization and translation costs (€200–€800 depending on needs)
Register in Réunion and apply for the appropriate titre de séjour: Within the first two months after arrival, register at the local Préfecture/OFII where required; obtain and renew your residence permit (carte de séjour) as required by your visa category. — Immediate registration; first carte de séjour processing 1–3 months locally — Administrative fees ~€200–€300 for card production; additional local registration fees may apply
Establish habitual residence and integration (work, housing, social security contributions, French language learning): Live and work in Réunion, pay taxes and social contributions, enroll in language courses to reach at least B1 and gather documentation proving continuous residence (leases, pay slips, social security statements). — Continuous for minimum 5 years (may be reduced in special circumstances) — Living costs (housing, etc.) variable; language course and testing €200–€800
Collect and legalize civil status documents and prepare naturalization dossier: Order certified birth/marriage certificates, obtain apostilles or legalizations, have documents translated by a sworn translator, prepare letters of support and proof of integration. — 1–6 months (dependent on issuing authorities in country of origin) — €200–€1,000 depending on number of documents and translation needs
Submit naturalization application to Préfecture or DDI and attend interview: File the application with required documents. Attend an interview on integration and take the language test if not already certified. — Application logged within weeks; administrative decision typically 12–24 months — Official fees are low (often <€100) but anticipate legal assistance or translation fees as above; total supplementary costs €500–€2,000
Receive decision and apply for French passport and national identity card: If naturalization is granted, register as a French citizen, apply for a French passport and carte nationale d’identité at the local mairie or prefecture services. — Passport issuance typically 2–4 weeks after registration — Passport fees vary; standard administrative costs €86–€100 (if applicable) + photo and travel to offices

Accelerated routes (marriage to a French citizen or exceptional cases)

If marrying a French citizen: ensure formal civil marriage and residency requirements: Marry under French civil law (in France or registered abroad) and ensure you and your spouse meet cohabitation and continuity conditions. Marriage shortens some requirements but you must generally show 4 years of marriage with proof of stable relationship and integration. — Marriage process varies (1–6 months); eligibility for naturalization by marriage often after 4 years of marriage (reduced to 3 years if spouse has been registered abroad under some conditions) — Civil marriage administrative costs minimal; legalisation/translation costs if foreign documents are needed €200–€800
Gather stronger integration proof and French language evidence: Prepare language certification (B1) and documentation proving the durability of the marital union and integration (joint tax returns, shared residence, birth certificates of children, social security records). — Months depending on document availability and language training — Language test and training €200–€800
File application for acquisition of nationality by declaration (marriage pathway) at the prefecture: Submit the dossier specifically designed for spouses of French nationals, attend interview and provide requested evidence of the relationship and integration. — Processing typically 12–18 months — Administrative fees low; expect document/translation/legal support costs €500–€2,000
If accepted, register and obtain French passport: Complete civil registration steps and apply for identity documents and passport as a French citizen. — Passport issuance 2–4 weeks after nationality registration — Standard passport/ID fees ~€86–€100 plus incidental costs

Pros & Cons
