The B2 bottleneck: what the 2026 citizenship rule asks of professionals, and what it takes to clear it

Published on 9 October 2026. Sources checked on 7 October 2026.

In 2026, the whole French naturalization process became harder. It used to be a file with a language check attached, and it is now a language exam with a file attached. A bottleneck was added at the start of the process, and people who would qualify on paper, with the years of residence, the job and the clean record, are now waiting at it, or blocked by it.

That bottleneck is the B2 in French, spoken and written. It weighs most on professionals, because they have the least spare time to reach a standard most of them have not been tested on since their last exam at school, and because nothing in their working week trains the exact skills the exam measures.

I should say where I stand before going further. I am a French coach and I prepare English speakers for the DELF B2 and the TCF. I have not yet seen a student through the whole citizenship process, so I will not describe the prefecture from the inside. What I can describe is the B2 itself, because getting professionals to that level on a fixed date is my job, and the rest of this piece separates the two: what the official sources say about the process, and what I see in my sessions about the language.

What changed for applicants

The process changed in four ways in less than a year. Each line below links to the guide where I explain it in detail.

Change	Since	Who it concerns	The guide
Circular of 2 May 2025 tightening the conditions for nationality by decree	May 2025	Naturalization and reintegration by decree	How to get French citizenship
B2 in spoken and written French, instead of B1 (décret n° 2025-648)	Applications lodged and declarations made from 1 January 2026	Naturalization, reintegration and declaration by marriage	The language requirement
A civic exam to pass before you file	1 January 2026	Naturalization and reintegration by decree, not declarations	The civic exam
B2 for spouses as well	Declarations made from 1 January 2026	Declaration by marriage	Citizenship by marriage

The order matters as much as the content. For naturalization, the B2 proof and the civic exam certificate are documents of the file itself, so you cannot lodge your application and work on your French while it is being processed. The language now comes first, and the clock only starts once it is done.

What the first figures show

The Ministry of the Interior published its figures for 2025 this year. In 2025, 98,139 people acquired French nationality, 5.3% fewer than in 2024. Acquisitions by decree, which means naturalization and reintegration, fell to 42,246, a drop of 13.5%, and the ministry attributes it in particular to the circular of 2 May 2025, which tightened the conditions for nationality by decree. Declarations by marriage went the other way, up 10.5% to 17,579.

Two cautions keep these figures honest. The drop in 2025 comes from the circular, not from the B2, because the B2 only applies to applications lodged from 1 January 2026, so its effect will not show before the 2026 figures, which the ministry usually publishes in January of the following year. And 2025 is lower than 2024, not lower than every recent year, since acquisitions by decree were at 40,064 in 2023.

What the figures do show is the direction. The route that now asks for a B2, a civic exam and tighter conditions is the one that shrank, and the delays are going the same way. The administration has 18 months from your récépissé to decide, or 12 months after ten years of habitual residence in France, and on 4 October 2026 Le Monde reported that naturalizations are seizing up even for foreigners with “high potential for our country”.

Why the B2 is the bottleneck

B1 asks you to manage everyday situations, to tell what happened and say what you would like. B2 asks you to understand speech that nobody has adapted for you and to defend a position on a subject you did not choose. In the DELF B2, that means presenting and defending a point of view for 5 to 7 minutes before a debate with the examiners, and writing an argued text of at least 250 words in one hour. You need 50 out of 100 overall and at least 5 out of 25 in each of the four papers, so one weak skill can sink a good total.

Many applicants have lived in France for years, they work, and they handle the administration and the school gate in French. Their French is real, but it is the French of their own week, and the exam measures what that week never asks of them, which is arguing on an imposed topic against the clock while a stranger pushes back. For a professional, the difficulty lies in finding regular hours for ten weeks or more to train skills that work does not train, much more than in any lack of ability.

The B2 bar, seen from my sessions

My own figures are small, so I will give them as they are. In 2026, five students I coached individually sat the DELF B2, and all five passed. One more is waiting for results. About twenty others reached the level on full mock papers, by my assessment, without sitting the exam. None of them was a citizenship candidate, because the citizenship work started this year, and I will add their results to this page when they come.

What these students had in common was a fixed exam date and a short preparation, usually ten to twelve weeks. I prefer ten weeks of narrow focus on what the exam asks, because a timeline forces choices that open-ended lessons never force.

C. was an average B1 when we started, in early September. He needed a B2 to apply for internships in Paris, where his partner lived. We had two sessions a week, he blocked time for his own practice between them, and he followed the plan we had worked out backward from the exam date to the letter. He sat the November session, passed, and he now does his internship in Paris.

S. had learned French without any structure since moving to Geneva with her husband’s job. She picked things up fast but in no particular order, and she decided to put that knowledge in order and aim for the B2, for her confidence and for a CV that local employers would take seriously. She had doubts until the day she signed up, she followed the plan anyway, and she passed.

Neither of them was applying for citizenship, so their stories say nothing about the prefecture. They show what it takes to clear the language part with a job and a life around it, which is the part that now comes first.

Four profiles I see on the way to B2

The outdated B1. This person passed a B1, or was told years ago that B1 was enough, and finds out late that applications lodged since 1 January 2026 need a B2. They often start by asking which exam is the easiest, when the useful question is which of their four skills is still below B2. So we start with a diagnostic of all four, and we keep three goals apart: reaching a real B2, learning the format of the exam they choose, and doing the paperwork.

The uneven candidate. Some read their emails and write careful texts but lose most of their French in a spontaneous conversation, and others talk easily but cannot structure a formal text. When they tell me their French is quite good, they are describing the situations where they already feel comfortable. Because the DELF eliminates anyone below 5 out of 25 in a single paper, we find the weakest skill and put it under pressure: a two-minute answer without notes, a recording at native speed heard once, a 250-word text in one hour, questions they did not prepare.

The functional B1. This is the person who has lived in France for years and gets everything done, at work, in shops and with the family, and who reasonably assumes that this is B2. In their answers I hear plenty of French with no argument structure: je suis d’accord, c’est important, and then nothing about why, no precise example and no other point of view. We work on one structure that serves the oral and the written paper alike, which goes from a position to a reason, an explanation and an example, and then to a concession and a response.

The candidate with an expiring TCF. The TCF IRN and the TEF IRN give an attestation valid for two years, while the DELF is a diploma valid for life. Someone who takes the TCF early, or before their weakest skill is at B2, can end up with an attestation that expires while the rest of the file is being prepared. Neither test is better in itself. A candidate who is already comfortably at B2 and needs a date soon may well choose the TCF, while one whose timetable is uncertain is safer with a diploma that does not expire. What matters is to count the months between the result and the filing date, with a margin.

The two steps the B2 does not cover

I have not prepared anyone for these two yet, so this part comes from the official sources and from my guides, not from my sessions.

The civic exam. For naturalization and reintegration, it has to be passed before you file. It has 40 multiple-choice questions in French, 45 minutes, and you need 32 right answers. The questions come from five official themes: the principles and values of the Republic, the institutional and political system, rights and duties, history, geography and culture, and living in French society. Declarations by marriage are not concerned. Its sessions, results and possible retakes have to fit into the same calendar as the B2, which is why I treat them as one timeline. The details are in my guide to the civic exam.

The interview. An admissible application leads to an interview at the prefecture, which checks your assimilation and your adherence to the principles and values of the Republic. This is where something I do see in my sessions could matter most. Under pressure, some candidates who know the answer on paper cannot reach it in spoken French: they give one-word answers, recite a prepared paragraph, or get lost when the question is put another way. In exam preparation I train against that by asking the same question in three different ways and interrupting with Pourquoi ? or Vous pouvez donner un exemple ?, and I expect the same training to serve at the prefecture.

Working back from your filing date

The applicants who will get through fastest are the ones who plan backward from the day they want to file, not forward from the day they feel ready. In practice, that plan has these steps, from the end:

The earliest realistic filing date, once every document is ready and valid.
The civic exam, with room for a retake.
The B2 result, with the time the test takes to issue it and, for a TCF or TEF, two years of validity that must still cover the filing.
The exam session itself, and its registration deadline, which can close well before the session.
Ten to twelve weeks of focused preparation, starting from an honest diagnostic of the four skills.

Put those on one calendar and the real filing date usually moves several months later than people expect, which is better known now than at the prefecture.

For lawyers and relocation advisers: checking a client’s French in five minutes

If you advise people on their file, you will meet clients who say their French is fine. Here is what I would do in five minutes before trusting that, without any test material:

Ask an open question in French on a subject they did not choose, such as remote work or the cost of housing, and listen for a position, a reason and an example.
Push back once with Pourquoi ? or Vous n’êtes pas d’accord ?, and watch whether they defend their view or retreat into oui, c’est vrai.
Speak at your normal speed and do not simplify. If they ask you to repeat more than once or twice, listening may be below B2.
Notice whether they switch to English when the conversation gets harder.

A client who struggles with two of these is probably not at B2 yet, and the earlier they know, the more realistic their filing date will be. If you want a precise answer for a client, the Bilan B2 is a 60-minute assessment that ends with an estimated score per skill, a written debrief and a study plan.
