B1 is a level French residence and naturalisation rules have long referred to, and it is where daily life in France genuinely changes: you stop depending on someone else to book a rendez-vous at the préfecture, read a letter from the CAF (the Caisse d'Allocations Familiales, the agency that pays family and housing benefits), or question a clause in your bail, and you can hold a real conversation about opinions and plans, not just facts. It is a genuinely bigger jump than A1→A2 — public estimates put it at roughly 350–400 guided hours in total — because it adds the connected grammar that turns isolated sentences into conversation: choosing correctly between the two main past tenses, the first uses of the subjonctif after il faut que, and the conditional for polite requests. Asagno's B1 path is built around the four skills the DELF B1 tests — listening, reading, writing and speaking — with a full practice exam under real timing once you are close, so exam day is not the first time you see that format.
What you'll learn
- Passé composé vs imparfait — choosing the right past tense for a single completed event versus an ongoing or habitual background
- The subjonctif after il faut que, bien que and je voudrais que — the forms B1 texts and exams expect you to recognise and use
- The conditional for polite requests and hypotheses: je voudrais, pourriez-vous, si j'avais le temps, je voyagerais
- Formal writing with vous: a letter or email to the préfecture, a landlord or an employer
- Integration vocabulary: the carte de séjour, the préfecture, the CAF, the médecin traitant, the bail
- Full practice exams matching the DELF B1 format, with a server-timed clock and AI feedback on writing and speaking
The B1 grammar point that trips up almost everyone
"Je regardais la télé quand le téléphone a sonné." — "I was watching TV when the phone rang." Regardais (imparfait) is the ongoing background; a sonné (passé composé) is the single, completed event that interrupted it. Choosing between these two past tenses is the classic B1 stumbling block in French — exactly as in Italian and Spanish — and one of the grammar points exams test most often.
"Quand j'étais petit, j'allais à la plage chaque été, mais l'année dernière, je suis allé à la montagne." — "When I was little I used to go to the beach every summer, but last year I went to the mountains." A useful shortcut for Arabic speakers: the imparfait often corresponds to كان + present verb (كنت أذهب), and the passé composé to the simple past (ذهبتُ).
Frequently asked questions
Is B1 enough for French residence or citizenship?
Language requirements for residence cards and naturalisation are set by French authorities and can change — this page is general guidance, not legal advice. As a broad orientation, French naturalisation has for years been associated with a B1 level in speaking and writing, but recent French immigration legislation has been revising the expected levels for several residence and naturalisation routes, and Québec/Canada, Belgium and Switzerland each run their own separate systems. Confirm the current requirement for your specific situation with the préfecture, the consulate or the relevant office before relying on any level.
How is the exam prep different from the regular B1 lessons?
The lessons build the language; the French B1 exam-prep pack adds a full practice exam under real timing, following the DELF B1 section structure (compréhension de l'oral, compréhension des écrits, production écrite, production orale), with an AI examiner scoring your writing and speaking against a clear rubric.
I live in Belgium or Québec, not France — is this still the right French?
The grammar and the core vocabulary are the same wherever French is spoken, and the DELF is recognised internationally. What changes is administrative vocabulary — the préfecture, the CAF and the carte de séjour on this page are specific to France — plus some everyday words and accents, so expect to pick up local terms once you are there.
