German language requirement for citizenship: how to prove B1

To become a German citizen you must prove German at level B1 of the Common European Framework of Reference (CEFR), both spoken and written (section 10(4) of the Nationality Act, StAG). The easiest way is a language certificate – for example the Deutsch-Test für Zuwanderer (DTZ) with a B1 result. A German school-leaving certificate, completed vocational training in Germany or a degree completed in German at a university in Germany also count. There are exceptions for children under 16, the guest-worker generation and people who cannot reach B1 because of illness, disability or age.

What B1 means in practice

B1 is the first “independent user” level. You understand the main points when people speak clearly in standard German about familiar topics such as work, family, official matters or leisure. You can handle most everyday situations, describe experiences, give brief reasons for your opinion and write simple connected texts – an email to your landlord, say, or a complaint. Your German doesn't have to be perfect, but you need to make yourself understood in speech and in writing.

Which proofs are accepted

Some naturalisation authorities (Einbürgerungsbehörden) also run their own language test. Ask yours whether that's an option and which proof it prefers.

Exceptions: who needs less proof, or none

• Children under 16: age-appropriate language development is enough. From 16, B1 generally applies.
• Guest-worker and contract-worker generation: if you came to West Germany under a recruitment agreement by 30 June 1974, or to the GDR as a contract worker by 13 June 1990, you only need to get by in everyday spoken German without significant problems. The same applies to spouses who joined you within a reasonable time (as a rule, within ten years). An A1 certificate is enough as proof; otherwise the authority checks your German in a conversation. You need neither a written test nor the citizenship test.
• Hardship (section 10(4a) StAG): if you cannot reach B1 despite serious and sustained efforts, or it is permanently much harder for you, the authority can accept everyday spoken German instead. The citizenship test is then waived too. You have to show your efforts, for example with certificates from courses you actually attended – simply enrolling is not enough. A typical case is caring for a close relative; according to the Federal Interior Ministry's guidelines, looking after children is not enough on its own.
• Illness, disability or age (section 10(6) StAG): if these prevent you from reaching B1 or taking the citizenship test, the requirement in question is waived. The law makes this mandatory – it is not at the authority's discretion. Reaching a certain age is not enough on its own, though, and you will usually need a medical certificate.

The easier rules for older applicants and the guest-worker generation are covered in German citizenship for older people.

B1 and the citizenship test are separate

People often mix up the two. The language certificate shows that you speak German. The citizenship test, by contrast, checks your knowledge of law, society and history: 33 questions, 60 minutes, pass mark 17. A B1 certificate does not replace the test, and the test does not replace B1.

There are overlaps that can save you effort, though:

• A German school-leaving certificate (at least a Hauptschulabschluss) counts as language proof and also exempts you from the citizenship test.
• The “Leben in Deutschland” test at the end of the integration course counts as the citizenship test if you answer at least 17 of 33 questions correctly. See the “Leben in Deutschland” test vs. the citizenship test.
• Being exempt from the test doesn't automatically exempt you from the language requirement. Check both separately, for instance with who doesn't have to take the citizenship test.

How to prepare for B1

1. Find out where you stand, for example with a placement test at a language school or adult education centre (Volkshochschule).
2. Check whether an integration course is open to you. It ends with the DTZ and the “Leben in Deutschland” test, so one course can give you both proofs. Courses and exam centres are listed on BAMF-NAvI.
3. Choose your exam provider: DTZ, telc, Goethe or ÖSD. Prices are set by the provider. With Goethe and ÖSD you must pass every module.
4. Practise writing and speaking in particular, such as short emails and conversations about everyday topics. Both tend to get neglected when you study alone.
5. Book in good time – popular exam dates can fill up quickly.
6. Study for the citizenship test at the same time – the questions build your vocabulary too. A study plan helps you combine both.
7. Keep the original certificate safe and bring it to your appointment with the authority.

C1 no longer speeds things up

From 27 June 2024 to 29 October 2025, people with C1 German and special integration achievements could naturalise after just three years. That fast track was abolished on 30 October 2025. Everyone now needs at least five years of residence, whether they prove B1 or C1. The full story is in German citizenship after 3 years.

A higher certificate still does no harm: it safely meets the B1 requirement, helps at work and makes the interview at the authority easier. But if you're learning only for naturalisation, B1 is enough. Every other condition is listed in German citizenship requirements.
