Quick Answer
Standard French naturalisation is usually 5 years of legal residence on a qualifying titre de séjour, plus DELF B2 (since January 2026) and a passed examen civique (40 questions, 32/40) before you file. Student time often counts at 50%; working-holiday time usually does not. Fast tracks exist for some French-university graduates (about 2 years of post-grad residence), spouses, parents of a French child, and refugees — each with extra conditions. Filing is often free of stamp duty. Verify clocks, permits, and documents with your préfecture and Service Public; this is an editorial map, not legal advice.

Most France-citizenship pages jump straight into DELF B2. That is the language bar — not the pathway. This hub is the residency clock, which permits count, the civic exam, the préfecture interview, and the dossier. Exam format lives on the satellites linked above.
The expensive mistake is treating every year on French soil as a year toward citizenship. Student time is often halved. A working-holiday visa usually does not count. A long absence can reset the clock. Get the permit arithmetic right before you spend months on B2.
Who can apply: the 5-year standard
For naturalisation by decree, the usual rule is 5 years of habitual, legal residence in France on a qualifying residence permit. The clock is about stable life here — work, tax, housing — not tourism with a long visa.
You also need to be of age, of good character, and able to show assimilation into the French community (language, civic knowledge, interview). Those boxes are later in this guide. Start with whether your titre actually counts.
Which titres de séjour usually count
The table is a planning aid, not a promise. Préfectures look at the legal basis of each card and whether residence stayed continuous. Verify your category on Service Public and with the office that issued your permit.
| Titre / status | Usually counts toward the 5 years? | Planning note |
|---|---|---|
| Salarié / salarié détaché (work) | Yes | Standard employment path |
| Passeport talent | Yes | Talent / skills cards are usually qualifying |
| Entrepreneur / profession libérale | Yes | Keep tax and activity evidence clean |
| Vie privée et familiale (VPF) | Yes | Family cards usually count; keep the family link current |
| Étudiant | Often 50% | Student years are commonly counted at half — confirm locally |
| Working holiday / PVT | Usually no | Treated as temporary, not stable residence |
| VLS-TS (long-stay visa as permit) | Only after conversion | Visa year typically starts counting once validated and converted into a titre |
| Visiteur | Usually no | Visitor status is not a naturalisation clock |
If you stacked statuses — student, then salarié, then passeport talent — ask the préfecture how each period is counted. Do not add calendar years in your head and call it five.
Absences: the ~6 months/year rule of thumb
Long trips can interrupt habitual residence. A common planning rule of thumb is to stay under about six months away in a year. The legal test is whether your life in France stayed continuous — housing, tax, work — not a hard stopwatch on every boarding pass.
Fast tracks (shorter than 5 years)
France shortens the clock for some people. These are not loopholes. Each one has extra evidence, and the préfecture can still refuse on integration or character grounds.
French university graduate — about 2 years
If you completed two years of higher education in France and hold a French diploma, the five-year requirement is often reduced to about 2 years of subsequent residence — typically on a work or talent permit after graduation, not while you are still on a student card. Confirm how your diploma and post-grad work years are counted; practice is not identical in every préfecture.
Student time before the diploma may still be halved. The fast track is the post-grad work period, not “I studied in Lyon, so I file in year two of my master’s.”
Spouse of a French citizen
Marriage to a French citizen is usually a déclaration route, not the same décret naturalisation file. Typical planning figures are four years of marriage if you live in France together, longer if you lived abroad for part of the marriage — confirm the current text on Service Public.
The sensitive part is communauté de vie — actually living together. Separate addresses, long solo postings, or a paper marriage with no shared life can delay or block the file. Language and civic requirements still apply under the 2026 rules. Verify living-together evidence (lease, tax, insurance) before you treat this as a shortcut.
Parent of a French child
A parent of a French minor may have a déclaration path if you have lived in France, hold parental authority, and meet the residence period in force when you file. This is not automatic from the child’s passport. Check the current Service Public page for parents; do not copy a forum timeline.
Refugee / stateless
Recognised refugees and stateless persons often have the duration-of-residence requirement reduced or waived. You still need language, civic proof, and the rest of the dossier. Protection status is not a skip-the-interview card.
Exceptional service
Exceptional services to France can shorten the clock. It is rare, discretionary, and not a DIY category. If this might apply, take qualified counsel — do not build a five-year plan around it.
Language: DELF B2 since January 2026
From 1 January 2026, naturalisation language proof is DELF B2 (or an accepted B2 equivalent). It was B1. B1 still matters for the carte de résident; it is no longer enough for citizenship.
| Goal | Usual CEFR level | Typical proof |
|---|---|---|
| First carte de séjour pluriannuelle | A2 | DELF A2 / accepted A2 test |
| First carte de résident | B1 | DELF B1 / accepted B1 test |
| Naturalisation (citizenship) | B2 (since Jan 2026) | DELF B2, DALF, or TCF/TEF at B2 with a valid date |
Accepted certificates commonly include DELF B2 and DALF (lifetime diplomas) and TCF / TEF at the required level. TCF and TEF are often time-limited (commonly about two years). If your naturalisation calendar might slip, a DELF B2 diploma is the paper that does not expire. Confirm the exact list your préfecture accepts — it can name specific TCF/TEF variants (for example TCF IRN).
DELF scoring canon, in one line: 50/100 overall and a note éliminatoire of 5/25 per skill. Four papers (listening, reading, writing, speaking), 25 points each. A high total still fails if any skill sits under 5. Full format, timing, and prep: DELF B2 exam structure 2026. Citizenship context and the B1→B2 change: DELF B2 for French citizenship.
Exam fees are typically around €150–200 depending on the centre. Treat that as a band, not a quote. Book early; B2 sessions fill.
Examen civique (since January 2026)
Since 1 January 2026 you also need a passed examen civique before you file naturalisation. It is a civic QCM, not a language diploma. Passing DELF does not skip it.
Format in force: 40 questions, 80% to pass (32/40), about 45 minutes, in French. Sit it before the dossier goes in — the attestation is part of the file, not a follow-up after the interview.
Some people are exempt (renewals of a card you already hold, certain protection statuses, some applicants over 65 — the official list moves). Do not self-exempt from a blog sentence. Check Service Public (examen civique).

Integration assessment and the préfecture interview
Naturalisation is not a stamp you buy after five years. The préfecture checks whether you actually live in France and share the Republic’s basic rules. That shows up in the file (work, tax, housing, CIR if you signed one) and in an entretien d'assimilation — a conversation, not a second QCM.
Expect questions about your job, family, housing, why you want French nationality, and what laïcité, equality, and voting mean in daily life. You speak French. Bring originals of the documents you already filed. Short, concrete answers beat speeches.
This is not designed to trap you. It is designed to see whether the person on the form matches the person in the room. If your French is only exam-French, practise talking about your real life — commute, school, taxes — before the date. If something in the file is messy (a gap in permits, unpaid tax), fix it before the interview rather than explaining it on the day.
How to apply: steps, documents, timeline
You file with the préfecture (or a designated platform) for your place of residence. Consular filing applies if you live abroad on a qualifying path — most readers of this hub live in France.
Typical sequence
- Confirm your clock: qualifying titres, absences, and any fast-track category — in writing if the préfecture will give it.
- Pass DELF B2 (or accepted equivalent) and keep the diploma or still-valid TCF/TEF.
- Pass the examen civique and save the attestation.
- Assemble civil status and residence proof — see the table. Foreign acts usually need apostille (or legalisation) and a sworn French translation.
- Submit the complete file on the channel your préfecture names (often an online dépôt, then originals on request).
- Attend the interview when summoned. Answer from your real life, not from a memorised script.
- Wait for the décret — then complete any remaining steps the letter names (oath / ceremony where required, then passport).
Document table (typical)
Lists differ by préfecture and by family situation. Use this as a packing list, then match it to the live Service Public / préfecture checklist.
| Document | Usually required? | Notes |
|---|---|---|
| Passport + current titre de séjour | Yes | Plus copies covering the whole residence period |
| Birth certificate | Yes | Recent copy; apostille + sworn FR translation if issued abroad |
| Proof of address | Yes | Lease, bills, tax — consistent with the titre |
| Avis d'imposition / tax evidence | Usually | Several years if you have them |
| Work / resources | Usually | Contracts, payslips, or other lawful resources |
| Language certificate | Yes (unless exempt) | DELF B2 / DALF / still-valid TCF or TEF |
| Examen civique attestation | Yes since Jan 2026 (unless exempt) | Must be in hand before filing |
| Criminal records | Yes | France plus other countries of residence — freshness rules apply |
| Family civil status | If relevant | Marriage, divorce, children’s certificates |
| Photos / identity forms | Yes | Follow the current préfecture spec |
Processing timeline (soft ranges)
There is no single national stopwatch. Planning ranges candidates often hear, once the file is complete:
| Stage | Soft range | What it means |
|---|---|---|
| Completeness check | Weeks to a few months | Missing translations are the usual delay |
| Interview date | After the file is complete | Queue length varies by département |
| Decision / décret | Often ~12–18 months | Some files are faster; some run longer — not a guarantee |
| Passport after approval | Weeks, once you have the decree paperwork | Book the appointment; do not travel on assumptions |
A “complete” file is the one the préfecture accepted, not the one you uploaded. If they ask for a new birth-certificate date or a missing payslip, the clock you care about has not started. Verify current ranges locally — 2026 backlogs are not uniform.
What it costs (soft ranges)
Naturalisation filing is often free of stamp duty — check Service Public before you pay anyone who claims a government filing fee. You still pay exams, translations, and (if you want one) a lawyer.
| Item | Soft range | Notes |
|---|---|---|
| Préfecture filing / stamp duty | Often €0 | Verify on Service Public — do not assume a timbre |
| DELF B2 (or equivalent) | ~€150–200 | Centre-dependent; retakes cost again |
| Examen civique | Confirm locally | Separate booking from DELF; fee is not the language exam |
| Apostilles + sworn translations | Hundreds of €, file-dependent | Every foreign civil-status act adds cost |
| Criminal-record extracts | Usually modest | Plus postage / consular fees if ordered from abroad |
| Lawyer (optional) | Wide range | Useful for messy permits or family files; not required for a clean 5-year salarié path |
Budget the language exam and translations first. Those are certain. Treat legal fees as optional unless your permit history is irregular.
Dual citizenship
France generally allows dual nationality. You are not asked to renounce your original passport as a condition of French naturalisation. That is the French side.
Your original country may not allow it. India and China, among others, often treat a foreign naturalisation as loss of the original nationality — or make a second passport legally awkward. Check that law before you file, not after the décret. This guide does not give home-country legal advice.
Frequently asked questions
Is French naturalisation still 5 years in 2026? Yes for the standard décret path: usually 5 years of legal residence on a qualifying titre. Some graduates, spouses, parents of a French child, and refugees have shorter or different routes — verify your category. Do not apply another country’s residency clock to France.
Does time as a student count? Often at 50%. Working-holiday / PVT time usually does not count. A VLS-TS typically starts counting only after validation and conversion into a titre. Confirm with the préfecture.
Is DELF B1 enough for citizenship? Not for standard naturalisation from January 2026. You need DELF B2 (or an accepted B2 equivalent). B1 remains the usual level for a first carte de résident.
What score do I need on DELF B2? 50/100 overall and at least 5/25 in each skill (note éliminatoire). One weak paper fails the diploma even if the total looks fine.
Do I need both DELF and the examen civique? Yes for most naturalisation files filed under the January 2026 rules. They are separate exams. Soft exemptions exist — check Service Public, do not self-exempt.
Is it free to file naturalisation? Filing is often free of stamp duty. Check Service Public for the current rule. You still pay language and civic exam fees, translations, and any optional legal help.
Does France allow dual citizenship? France generally does. Your original country may not — India and China are common examples where you must check before you apply.
How long does the préfecture take? Plan in soft ranges: often around 12–18 months from a complete file, sometimes longer. Completeness checks and interview queues vary by département.
Can I apply on a working-holiday visa? Usually no. PVT / working-holiday time is generally not qualifying residence. Convert to a work, talent, or family titre and restart the count from what the préfecture will recognise.
What if I fail DELF B2? Retake after you fix the weak skill — the 5/25 floor is the usual trap. Citizenship filing waits on a pass. See /blog/what-happens-if-you-fail-citizenship-language-exam.
