You filed your French naturalization application, your TCF IRN or DELF B2 certificate is in hand, and now you're waiting for the summons to your assimilation interview. And then everyone tells you something different: "they asked me who De Gaulle was", "mine was mostly about laïcité", "I had to talk about La Marseillaise".
Here we lay out what this interview is actually for, what gets evaluated, the questions that come up most often, how to prepare without drowning in 200 history dates, and the mistakes that sink applications even when the language level is solid.
The assimilation interview (entretien d'assimilation) is mandatory for any French naturalization by decree. It takes place at the préfecture (the local government administrative office in France) or at the French consulate (abroad) and lasts between 30 minutes and 1 hour 30. The agent evaluates 4 things: (1) your spoken French in real situations, (2) your knowledge of French history, geography and institutions, (3) your support for republican values (laïcité - the French principle of secularism, equality, freedom), (4) your personal integration journey. Holding a B2 French test certificate guarantees nothing if you can't answer questions about the Vème République (Fifth Republic, the current French political system since 1958), the national motto or laïcité. You prepare with the livret du citoyen (citizen's booklet, available free on the Ministry of the Interior's website) and oral practice of French at natural speed.
1. What this interview really is
The assimilation interview, sometimes called the "naturalization interview" or "individual assimilation interview", is a mandatory step in the naturalization-by-decree procedure. It happens after your complete application has been filed and your language test results (TCF IRN, DELF B2, DCL or DFP B2) have come in.
You'll receive an official summons stating the date, time and location. In France, that's at your local préfecture (or sub-préfecture). Abroad, it's at the relevant French consulate.
The agent who meets with you is a civil servant trained to assess your integration, not a French teacher. They take notes throughout the interview and write a report that goes to the Ministry of the Interior along with your file. That report carries far more weight in the final decision than your raw TCF score does.
2. The 4 things being evaluated
A. Spoken French in real-world situations
The agent speaks to you at normal speed, with natural turns of phrase, sometimes throwing in unexpected questions to see how you react. This is not slowed-down classroom French. If you need 5 seconds to process every question before answering, that's a bad sign.
What's expected: you understand the questions the first time around, you answer in full sentences (not just "yes" or "no"), you can ask for a rephrasing if something is unclear, and your accent doesn't get in the way of being understood.
B. History, geography, institutions
No multiple-choice quiz, but general culture questions. The classics:
- Who was Charles de Gaulle? What role did he play during World War II?
- Name the presidents of the Vème République (at least the last 3).
- What is the motto of the Republic? What does each word mean?
- Name two symbols of the Republic (Marianne - the female allegory of France, the flag, the anthem, the rooster, etc.).
- In what year did the French Revolution take place? What happened on 14 July 1789?
- Name 3 French regions and their administrative capital.
- What are the main rivers? The mountain ranges?
- How does the French Parliament work? What's the difference between the National Assembly and the Senate?
C. Republican values
Beyond dates, the agent wants to confirm that you genuinely subscribe to the core values. Typical questions:
- What does laïcité (French secularism) mean in France? Why does it matter?
- What does gender equality look like in France?
- What are the rights of a citizen? And the duties?
- What's your view on freedom of expression?
- What is the role of public schools?
The agent isn't looking for a textbook-perfect answer. They want to understand where you stand personally and to make sure you're not in radical disagreement with these values.
D. Your personal integration journey
This is the most personal part. The agent asks you about your life in France: your job, your family, your social ties, your activities, what you actually do here day to day.
- Why do you want to become French?
- What do you enjoy about France?
- Who do you speak French with on a daily basis?
- Are you involved in any association, club or activity?
- How are things going at school / at work / in your neighborhood?
- Do you have family in France?
3. The livret du citoyen - your main study tool
The Ministry of the Interior publishes a livret du citoyen (citizen's booklet) that you can download for free from the official website. This is THE document to study. It's about 30 pages long and covers:
- French history (key dates, political regimes)
- Institutions (president, government, Parliament, judiciary)
- Republican values
- Geography (regions, rivers, mountains, climate)
- Culture (Marianne, anthem, flag, national holidays)
- Citizens' rights and duties
Read it 2 or 3 times. Don't memorize it word for word - agents can spot recited answers a mile off. Understand it, connect the dots between concepts. If you can tell the story of the last 200 years of French history in 3 minutes, you're ready on this front.
4. How to prepare (a 30-day method)
Week 1 - History and institutions
- Read the livret du citoyen all the way through once
- Watch 2-3 short videos on the Vème République (the YouTube channel "Histoire à la carte" is a good option)
- Memorize the last 5 presidents and recent prime ministers
Week 2 - Geography and culture
- Learn the 13 regions of metropolitan France and their administrative capitals
- Memorize the rivers (Seine, Loire, Rhône, Garonne, Rhin) and the mountain ranges (Alpes, Pyrénées, Massif central, Vosges, Jura)
- Know the symbols (motto, flag, anthem, Marianne, Gallic rooster, national holiday on 14 July)
Week 3 - Republican values
- Study laïcité in depth (the 1905 law on the separation of Church and State, public schools, public service)
- Be ready to talk about citizens' rights and duties
- Think about what you genuinely believe regarding gender equality and freedom of expression
Week 4 - Oral practice and personal story
- Practice talking about your own journey in French at natural speed
- Ask a French-speaking friend to throw random questions at you
- If you don't have a French-speaking friend on hand, this is exactly what 360 French Immersion from HelloFrench trains: 60 authentic dialogues with pronunciation scoring and rephrasing exercises. You build the ability to understand and respond at natural speed - exactly what the interview demands.

5. The mistakes that sink applicants who already have a B2
- Reciting without understanding. If the agent asks "why 1789?" and you fire off 4 memorized dates without explaining the context, that's a deal-breaker.
- Not being able to talk about yourself. A lot of applicants prepare French history and forget to prepare their own story in France. Why you came, what you do, who you know.
- Disagreeing with republican values. If you express strong disagreement with laïcité, gender equality or freedom of expression, the report will be negative. Think it through carefully.
- Stiff, rehearsed French. You can have a B2 on paper and freeze the moment the agent switches topic or speaks a bit fast. Practice spontaneous French, not test-format French.
- Dress and attitude. Smart-casual minimum, on time, polite. This is an official interview, not a chat between friends.
- Lying about your situation. Agents cross-check against your file. If you claim a full-time job when your file says otherwise, you have a problem.
6. The day itself - typical sequence
You arrive 15 minutes early with your summons, your ID and your residence permit. You wait, sometimes a long time, in a waiting room. Eventually they call you.
Opening moment: the agent says hello, asks how you're doing, has you sit down. Use this to breathe and shift into French speaking-and-listening mode.
First block (10-20 min): questions about your life in France. Why you came, your work, your family, your daily routine.
Second block (15-30 min): questions about France itself. History, geography, institutions, values. This is where preparation pays off.
Third block (5-15 min): questions about why you want to become French and what French nationality means to you.
Wrap-up: the agent thanks you and may ask you to sign the charte des droits et devoirs du citoyen (Charter of Citizens' Rights and Duties). You leave without knowing the verdict - the final decision arrives by mail within 6 to 18 months.
