Two paths to French citizenship

French nationality law offers two main routes for foreign adults who want to become French citizens. Each has its own conditions and its own document checklist. Before you start collecting translations, identify which path applies to your situation.

By decree · Par décret

Naturalisation by decree

For foreign adults who have lived in France for at least 5 years (2 years if you completed higher education in France, or no waiting period if you served in the French armed forces). Also requires economic stability, French language proficiency (B1), and successful assimilation interview.

  • Legal basis: Article 21-15 of the Civil Code
  • 5 years continuous residence (2 years if studied in France)
  • Stable income, tax compliance
  • French B1 level required (TCF or DELF)
  • Assimilation interview at prefecture
  • Decision by the Ministry of the Interior
By marriage · Par mariage

Declaration by marriage

For foreign nationals married to a French citizen. You can apply 4 years after marriage if you have continuously lived together in France during that time; 5 years if there has been a period living abroad or less than 3 years of French residence before application.

  • Legal basis: Article 21-2 of the Civil Code
  • 4 years of marriage + joint residence in France
  • 5 years if any period abroad or short French residence
  • Same language & integration conditions
  • Declaration, not a decree · different file
  • French spouse must still be French at decision date

Documents required for all naturalisation cases

The following documents are required regardless of the path you choose. Foreign-language documents must be accompanied by a certified French translation by a sworn translator registered with a French Court of Appeal.

Documents you DON'T translate (French or already in French)

  • Completed ANEF application form (generated online).
  • Colour passport photo (ID standard).
  • Copy of your valid residence permit (titre de séjour).
  • Proof of address in France (rent, utility bill, bank statement less than 3 months old).
  • Last 3 years of French tax returns (avis d'imposition).
  • Last 3 pay slips + employment contract.
  • French language certificate (TCF, DELF, diploma).
  • Any documents issued by French administrations.

Documents to translate · the mandatory list

These are the documents that almost always require certified French translation (by a sworn translator) for naturalisation:

Birth certificate
Long-form, less than 3 months old, apostilled (if non-EU). Details →
Marriage certificate
Required if married. For naturalisation by marriage, the French marriage certificate plus any prior foreign marriage records.
Criminal record (country of origin)
Police clearance / good conduct certificate / FBI IdHSR / DBS / RCMP check. Must be less than 3 months old.
Criminal records (other countries)
From every country where you lived 6+ consecutive months in the last 10 years. One per country.
Divorce judgment
If applicable · full court decree with certificate of finality. Required if previously married.
Diploma or work certificate
University degree, professional certificate, or long-term employment attestation · to evidence integration.

Depending on your personal situation, you may also need to translate:

  • Children's birth certificates (if you are including minor children in your file);
  • Civil status documents for deceased parents (for certain nationality transmissions);
  • Previous residence permits from other countries;
  • Foreign pension or social security documents (if applicable);
  • Adoption orders (if adopted);
  • Change of name orders.

Important timing: document age & apostille

The 3-month rule

For naturalisation, your birth certificate must be less than 3 months old at the time of filing. The criminal record(s) have the same requirement. This means you cannot use documents you translated years ago · you need fresh copies, apostilled, and translated, all within a few months of your application.

Marriage certificates and divorce judgments are typically not subject to the 3-month rule, because they refer to past events that don't change. But check your prefecture's specific checklist · some prefectures apply the rule more strictly than others.

Apostille for non-EU documents

All documents from non-EU countries require an apostille (or double legalisation if from a non-Hague country) before translation. The apostille must be on the original document · the translator then translates both the document and the apostille.

Canada joined the Hague Convention on 11 January 2024 · Canadian documents now require a Global Affairs Canada apostille (previously, double legalisation). US, UK, Australia, NZ, India, South Africa have been Hague parties for many years. Nigeria, certain other African countries, and some Middle Eastern states are non-Hague · double legalisation via the French Embassy applies.

Plan backwards: if your prefecture appointment is in 6 weeks, you need the birth certificate translated no more than 3 months before that date. Counting apostille wait times (up to 8 weeks in some US states), start the paperwork at least 10–12 weeks in advance.

Where to apply

Since 6 February 2023, most naturalisation files are submitted online via the ANEF platform (administration-etrangers-en-france.interieur.gouv.fr). Here is the submission map:

SituationWhere to submit
By decree, living in FranceANEF (online) or local prefecture / sub-prefecture (departments not yet on ANEF)
By marriage, living in FrancePrefecture of your department (currently paper procedure for declaration)
By decree, living abroadFrench consulate of your country of residence
By marriage, living abroadFrench consulate · special procedure with local declaration

After submission, you will be called for an assimilation interview at your prefecture or consulate. The interviewer checks your French language, your knowledge of French history, institutions and values, and your integration.

Processing time

French naturalisation is not fast. Expect 12 to 24 months between submission and final decision, with significant variation by prefecture:

  • Paris and Île-de-France: 18–24 months (highest volume of files).
  • Major cities (Lyon, Marseille, Toulouse, Bordeaux): 14–20 months.
  • Smaller prefectures: 12–15 months.
  • Consulates abroad: 15–24 months.
  • By marriage: typically 3–6 months faster than by decree at the same prefecture.

During this period, you may receive additional requests (compléments d'enquête) for more documents or a clarification interview. Keep your French residence permit valid throughout the procedure.

Common rejection reasons · and how to avoid them

Naturalisation files are rejected or returned for completion more often than people expect. Here are the main avoidable causes:

  1. Birth certificate more than 3 months old. Always request a fresh certified copy just before submission.
  2. Missing apostille. Non-EU documents need apostille on the original · apostilled after translation is too late.
  3. Missing criminal record from one country. If you lived 6+ months in Germany on exchange during university, you need a German Führungszeugnis · not just your home-country record.
  4. Insufficient French language proof. You need TCF or DELF at B1 level, or a French degree. No exceptions for English-speaking applicants.
  5. Unstable income. Long-term unemployment or irregular income can be a blocker. Prepare a clean 3-year tax history.
  6. Missing or badly-formatted translations. Translation by a non-sworn translator (US notary, UK solicitor, freelance) is automatically rejected. Use only French court-sworn translators.
  7. Translation not bound to source. The translation must be physically stapled and paraphed to a copy of the original. We do this as standard.
Pro tip: before submitting on ANEF, have your entire file reviewed by a specialised immigration lawyer or a certified accompaniment service. A 30-minute review can save you 12 months of back-and-forth with the prefecture.

Frequently asked questions

Which documents must I translate for French naturalisation?

Mandatory translations: your birth certificate (less than 3 months old, apostilled if non-EU), your marriage certificate if applicable, criminal records from your country of origin and from every country you lived in for more than 6 months in the last 10 years, divorce judgment if applicable, and a diploma or work certificate as proof of integration.

Additional documents may be required depending on your situation: children's birth certificates (if including them in the file), parents' civil status documents (for certain filiation cases), adoption orders, change of name orders, etc.

How long does French naturalisation take?

Processing time at the prefecture ranges from 12 to 24 months. Paris and Île-de-France are often slower (18–24 months). Naturalisation by marriage is typically faster (12–18 months) than naturalisation by decree. Consulates abroad are also at the longer end (15–24 months).

What is the difference between naturalization by decree and by marriage?

Par décret (by decree): the classic route via Article 21-15 of the Civil Code. Requires 5 years of continuous legal residence in France (2 years if you studied here), economic integration, French B1 language level, and a successful assimilation interview. Decision is taken by decree of the Prime Minister and Minister of the Interior.

Par mariage (declaration): available under Article 21-2 after 4 years of marriage to a French spouse with continuous joint residence in France. Extended to 5 years if there was any period abroad or insufficient French residence before application. This is a declaration, not a decree · the procedure is different and typically faster.

Must my birth certificate be less than 3 months old?

Yes. The prefecture requires a birth certificate issued within the last 3 months of submission. You need to request a fresh certified long-form copy from your country's vital records office, apostille it (if non-EU), then translate it · all within a few weeks before filing. We deliver translations in 48h to help you meet this deadline.

Do I need criminal records from every country I have lived in?

Yes. You need a police clearance certificate from your country of origin AND from every foreign country (outside France) where you have lived for more than 6 consecutive months in the last 10 years. Each record must be less than 3 months old, apostilled (if from a Hague country), and translated.

Example: if you are British, lived in Germany for 2 years, worked in Dubai for 8 months, and then moved to France, you will need: UK DBS + German Führungszeugnis + UAE police clearance + French police record.

How much does the full translation pack cost?

Our naturalisation pack covers 5 core documents (birth certificate, marriage certificate, criminal record, divorce judgment if applicable, diploma or work certificate) at €149 · a 25% discount versus €220 if ordered individually. Additional documents are €29–€39 each. All delivered in 48h with paper originals by tracked post.

Where do I submit my naturalisation application?

Since 6 February 2023, naturalisation by decree is submitted online via the ANEF platform (administration-etrangers-en-france.interieur.gouv.fr). Naturalisation by marriage is still generally a paper procedure handled at your prefecture or sub-prefecture. If you live abroad, the French consulate of your country of residence handles your application.

What are the most common reasons for rejection?

The main procedural reasons are: birth certificate older than 3 months, missing apostille, missing criminal record from a country where you lived 6+ months, insufficient French language proficiency (no TCF/DELF B1), unstable income or unclear professional situation, incomplete tax returns, and translations produced by non-sworn translators.

Substantive reasons for refusal (not just returns for completion): criminal convictions, concerns about assimilation, financial dependency on social benefits, or doubts on the sincerity of the marriage (for the "par mariage" route).
