The German Citizenship Language Requirement: B1, the Einbürgerungstest and How to Prepare

By Language Lab editorial team

German citizenship needs B1 German and the naturalisation test. What § 10 of the Nationality Act says, who is exempt, and a practical plan to reach B1.

What the law says

Section 10 of the Staatsangehörigkeitsgesetz (StAG) lists the conditions for naturalisation. A foreign national who has lived lawfully and habitually in Germany for five years is entitled to naturalise if, among other things, they commit to the constitutional order, hold a qualifying residence right, can support themselves and their dependants without certain social benefits, have sufficient knowledge of German (condition 6) and have knowledge of the legal and social order and living conditions in Germany (condition 7).

Section 10(4) makes the language condition concrete: it is met if you pass a language test at level B1. For children under 16, age-appropriate language development is enough. Section 10(5) says condition 7 is normally proven by passing the Einbürgerungstest; preparation courses exist but are optional. Section 10(3), which used to allow faster naturalisation for exceptional integration, is now marked as repealed.

What B1 German means in practice

B1 is the "independent user" level. You can understand the main points of clear standard speech about work, school and leisure, handle most situations while travelling, write simple connected text on familiar topics, and describe experiences, hopes and plans with brief reasons. For daily life in Germany that means: handling an appointment at the Bürgeramt, explaining a problem to your landlord, following a doctor's instructions and writing a short formal email.

Which test to take

The law asks for a passed B1 language test. Before booking, ask your local naturalisation office (Einbürgerungsbehörde) which B1 certificates it accepts. Our guides to the Goethe B1 exam and to choosing between telc and Goethe explain those exam formats.

How long it takes to reach B1

German is a Category II language in the US Foreign Service Institute's scale — about 36 weeks (828 class hours) of full-time training to professional working proficiency, which is above B1. Your pace depends on hours per week and how much German you use daily; living in Germany and speaking it at work is the biggest accelerator.

A preparation plan

• Start with speaking, not grammar tables: B1 is about using German independently in everyday situations.
• Practise the letter-writing task: complaints, requests and apologies are standard.
• Do timed listening practice with authentic announcements and dialogues.
• Take the Einbürgerungstest practice questions early — they're a separate hurdle.
• Rehearse real situations: Language Lab's German course uses a voice tutor for the Bürgeramt, doctor and landlord conversations B1 exams draw on.

What B1 German sounds like in real situations

Notice what these have in common: full sentences, a reason (weil, deshalb), a polite request (könnten Sie), and past or future time. That's the heart of B1. You don't need perfect case endings, but you do need to get your message across clearly and independently, without someone translating for you.

Mistakes that cost learners the B1 pass

• Memorising answers word for word: examiners ask follow-up questions, and scripted answers fall apart.
• Neglecting writing: a short formal message with a clear request, a reason and a polite closing is a standard B1 task.
• Only practising reading: listening to real, natural-speed German — announcements, radio, podcasts — is what trains your ear.
• Leaving the civic test to the end: it's a separate requirement with its own preparation.
• Waiting until the five years are almost up: language usually takes longer than people expect, so start in your first year.

A 12-month plan to B1

Months 1–3: pronunciation, everyday vocabulary and the present and perfect tenses, spoken every day. Months 4–6: modal verbs, subordinate clauses with weil and dass, and phone calls and appointments. Months 7–9: formal letters and emails, opinions with reasons, and the Einbürgerungstest topics. Months 10–12: timed mock exams, speaking practice with feedback, and booking your test. The plan flexes with your hours, but the order — speaking first, exam format last — works for almost everyone.
