German B1 for Citizenship and Residency: The Rules and the Hours

If you live in Germany, B1 is the level the law cares about most. It is the level for naturalisation and for the standard settlement permit, and it shortens the wait for permanent residence on the EU Blue Card. This post sets out which permit needs which level, what the official integration course actually consists of, and how to turn "B1" into a number of study hours you can plan around.

A note before the details: immigration rules change, and your local authority (Ausländerbehörde or Einbürgerungsbehörde) has the final say on your case. The rules below are taken from the statute texts on gesetze-im-internet.de and BAMF guidance, last checked on 30 September 2026. This is general information, not legal advice: before you book an exam or file an application, confirm the requirements for your permit with the authority handling your case.

Which level for which permit

German residence law defines its language levels by CEFR. Section 2 of the Residence Act (AufenthG) maps "einfache" knowledge to A1, "hinreichende" to A2, "ausreichende" to B1, "gute" to B2 and command of the language to C1. With those definitions, the main requirements are:

• Spouse joining a partner in Germany: the spouse must be able to communicate in German "at least in a simple way" (§ 30 AufenthG), which in practice means A1. There are exceptions, including spouses of EU Blue Card holders and of certain skilled workers.
• Standard settlement permit (Niederlassungserlaubnis): § 9 AufenthG requires, among other things, five years with a residence permit, 60 months of pension contributions and "ausreichende" German, which is B1.
• Settlement for skilled workers: § 18c(1) allows it after three years with a residence title (two if you trained or studied in Germany), again with B1, plus at least 36 months of pension contributions (24 after German training or study) and other conditions.
• Settlement for EU Blue Card holders: under § 18c(2), after 27 months of Blue Card employment with basic (A1) German, or after 21 months with B1. Here B1 is worth six months.
• Citizenship: § 10 of the Nationality Act (StAG) requires five years of lawful residence, "ausreichende" German, defined in § 10(4) as meeting the requirements of a B1 language exam, plus knowledge of the legal and social order, normally shown by passing the naturalisation test.

One recent change affects planning. The 2024 reform had added a three-year fast track to citizenship for people with exceptional integration, which required C1 German. That route has been abolished: the Bundestag passed the bill on 8 October 2025, and the change took effect on 30 October 2025. Five years and B1 is now the standard path for everyone applying under § 10. If you applied under the old three-year rule, ask your naturalisation authority how your application is being handled.

How you prove B1

For citizenship, BAMF's naturalisation page asks for B1 and notes that a B1 result on the Deutsch-Test für Zuwanderer (DTZ), taken at the end of the integration course, counts. Standalone B1 certificates from the major exam providers, such as the Goethe-Zertifikat B1 or telc Deutsch B1, are the other common route; check with your authority which certificates it accepts before you book.

The civics part is separate. The naturalisation test has 33 questions, you have 60 minutes, you pass with 17 correct answers, and it costs 25 euros. If you did the integration course, a score of at least 17 out of 33 on its "Leben in Deutschland" test also counts. For the settlement permit, § 9 says a successfully completed integration course satisfies both the language and the civics conditions.

The DTZ is a scaled test, and that matters

The DTZ is not a pass-or-fail B1 exam. According to BAMF, it certifies either A2 or B1, and to be awarded a level you must reach it in the speaking section and in at least one of the other two parts (listening and reading, or writing). If you miss B1, you can still leave with an A2 certificate, which is useful for some permits but not for citizenship.

Plenty of course participants finish at A2. In an answer to a parliamentary question (Bundestag document 20/15126, March 2025), the federal government reported 104,656 DTZ candidates reaching A2 in 2024, a preliminary figure. Completing the course hours does not guarantee B1, and speaking carries the most weight.

What the integration course actually contains

The integration course is the closest thing to an official estimate of how long B1 takes. According to BAMF's course leaflet (August 2026 edition):

• The general course has a language course of 600 teaching units and an orientation course of 100 units.
• A teaching unit (Unterrichtseinheit) is 45 minutes.
• The language course is six modules of 100 units: a 300-unit basic course and a 300-unit intermediate course.
• Special courses, for example for people who cannot yet read and write well, run to 1,000 units. Faster learners can take an intensive course.
• Self-paying participants contribute 2.29 euros per unit, paid module by module. Several groups are exempt, and others can apply for exemption.

Convert that to clock time and the language course is 600 × 45 minutes = 27,000 minutes, or 450 hours of classroom time. The full 700-unit course is 525 hours. At the self-payer rate, 700 units cost 700 × 2.29 = 1,603 euros.

Those 450 hours are classroom hours only. They do not include homework, the German you hear at work or the shops, or any time with series and podcasts. Learners who live in German, rather than only attending German classes, generally have a lot more total exposure than the course figure suggests.

How long B1 takes if you study on your own schedule

No official body publishes a precise hour count to B1 for every learner, and the integration course figure is a design target for a course, not a guarantee. Still, 450 hours of structured study is a sensible planning baseline for a beginner. Here is how it plays out at different weekly paces (pure arithmetic, assuming you keep the pace every week):

• 4 hours a week: 450 ÷ 4 = about 113 weeks, a little over two years.
• 6 hours a week: 75 weeks, about 17 months.
• 10 hours a week: 45 weeks, about 10 months.
• 20 hours a week (a full-time intensive course): about 23 weeks, under six months.

For context, the US Foreign Service Institute places German in Category II, at about 36 weeks or 828 class hours for English speakers to reach professional working proficiency (ILR 3), which is well beyond B1. Your first language matters too. A Dutch speaker will usually move faster than someone starting from Arabic or Vietnamese.

If your deadline is fixed, such as a Blue Card holder aiming for the 21-month settlement option, work backwards. Twenty-one months from your start date, minus a couple of months for exam booking and results, leaves about 19 months. 450 hours over 19 months (roughly 82 weeks) is about 5.5 hours a week. That is manageable alongside a full-time job, but only if it actually happens every week.

Where the hours should go

Because the DTZ requires B1 in speaking plus one other section, and standalone B1 exams test all four skills, a plan that is mostly apps and grammar drills tends to fall short at the oral exam. A balance that reflects how B1 is tested:

• Speaking, about a quarter of your time: a tutor, a conversation group or a language exchange. Practise with the official sample papers for your exam so the oral task formats hold no surprises.
• Listening and reading, about 40%: radio news in slow German, podcasts for learners, short articles. Comprehension grows fastest with material you can mostly follow.
• Writing, about 15%: short emails and messages of the kind the exams ask for (complaints, requests, replies to invitations).
• Grammar and vocabulary, about 20%: case endings, word order in subordinate clauses, separable verbs and the vocabulary of everyday administration.

These proportions are a starting point, not a formula. If a mock exam shows your writing is solid and your speaking is weak, move the hours.

Weekly time is easiest to check if it is logged as it happens. LangTrack records each session with its activity type and length, either as a two-tap repeat of a session you do often or with a start/stop timer, and the weekly recap shows whether you hit your target and how the time divided between speaking, listening and the rest.

A practical sequence

1. Find out which level you need and by when. Citizenship, settlement and the Blue Card shortcut all require B1, but at different points in your residence timeline.
2. Get placed. If you join an integration course, the provider gives you a free placement test. Otherwise, a mock A2 or B1 paper will show where you are.
3. Set a weekly hour target from the arithmetic above and keep to it for a month before you judge whether it is enough.
4. Take a full mock exam around 70 to 80% of the way through your plan, and focus the remaining hours on whatever it shows is weakest.
5. Book the real exam with enough margin that a retake would still meet your deadline.

If you later need B2 for work or university, the jump is significant; our Goethe-Zertifikat B2 preparation guide covers that exam. For general logging and milestones, see tracking your German learning progress, and if you have not moved yet, learning a language before moving abroad sets out a six-month plan.

The bottom line

B1 is the level for German citizenship and the standard settlement permit, and it saves Blue Card holders six months on the way to permanent residence. The official integration course budgets 600 teaching units, or 450 clock hours, of language instruction to get there, and many participants still finish at A2. Plan for at least that many hours, give speaking a real share of them, and check your weekly totals against the deadline.
