The authority also checks your declaration of commitment to the Basic Law and that your identity and nationality are clear. Naturalisation after three years no longer exists. An estimate from the law, not legal advice.

For naturalisation, section 10(4) StAG requires sufficient German: you have it if you meet the requirements of a language exam at level B1 of the Common European Framework of Reference, spoken and written. The usual proof is a certificate from a recognised exam, such as the German Test for Immigrants (DTZ) with a B1 result at the end of the integration course, telc Deutsch B1, the Goethe-Zertifikat B1 or an ÖSD exam at that level. A higher certificate such as B2 or C1 obviously also counts. Many authorities also accept a German school-leaving certificate, vocational training or a degree completed in German. Children under 16 only need age-appropriate language development. Former guest workers and contract workers and their spouses only have to communicate orally in everyday life. If someone cannot reach B1 despite serious efforts, the authority can also limit the requirement to everyday German; illness, disability or age exempt you entirely.

What counts as proof

Section 10(4) StAG refers to the level, not to a specific exam. In practice most people submit a certificate. The overview shows the usual routes; whether a school or vocational qualification is enough is up to the authority.

The exceptions in the law

Subsection 4, third sentence, eases the proof for one group: people who came to West Germany under a recruitment agreement by 30 June 1974 or to East Germany as contract workers by 13 June 1990 only need to communicate orally in everyday life without significant problems, and the same applies to their spouses. Subsection 4a opens a route for hardship cases, where learning is impossible or permanently much harder despite serious and sustained effort. In both cases the citizenship test is also waived. Subsection 6 exempts people entirely from the language and knowledge proofs if illness, disability or age makes them impossible; a medical certificate is then usual.

What a B1 exam asks of you

At B1 you understand the main points of clear speech on familiar matters from work, school or leisure, cope with most everyday situations, write simple connected texts and can briefly explain experiences, plans and opinions. Exams usually have listening, reading, writing and a speaking part, often with a partner. Exam centres set their own prices, which vary, so we do not quote a figure.

B1 is not a formal entry condition for the citizenship test, but it helps a lot, because the paper is in German only. Practising with the question catalogue also builds the vocabulary that many language exams test on society topics.

Common questions

Is the German Test for Immigrants (DTZ) enough for citizenship?

Yes, if the result is B1. The test at the end of the integration course certifies either A2 or B1, and only B1 meets the requirement. If you finished with A2, you can retake it or sit another recognised B1 exam, such as telc or Goethe.

How old can my language certificate be?

The law sets no expiry date, so a B1 certificate generally remains valid even after several years. The authority may still ask questions if it becomes clear in conversation that your German is well below B1. Keep the original safe, as not every exam provider issues replacements.

Do I also need to be able to write German?

Yes. For the standard proof, the exam counts as a whole: listening, reading, writing and speaking. Only in the special cases of the law, meaning former guest workers and their spouses or hardship cases, is everyday spoken German enough, and those groups then do not need the citizenship test either.
