Is B1 enough for citizenship or do I need C1? (Status 2025/2026)

The short answer: B1 is enough

For German citizenship, you need German at level B1 according to the Common European Framework of Reference for Languages (CEFR). C1 is not required. This was the case before the reform, and it remains the case today.

There was once a faster path: naturalization after just 3 years. For this path, you needed C1 German and special integration achievements. This exact path was abolished on October 30, 2025. Since then, there is no path requiring C1 anymore. Now everyone follows the standard path with B1.

If you are preparing for naturalization, B1 is your goal. You don’t need to prove anything beyond that linguistically.

Why some people have heard about “C1”

Between June 2024 and October 2025, there was what was called “turbo naturalization.” Those who had integrated particularly well could become German citizens after just 3 instead of 5 years. One of the requirements for this was German at C1 level.

In practice, it was rare: in 2024, fewer than 200 people used this path, while approximately 292,000 people were naturalized in the same year. Because the path was so rarely used, lawmakers removed it.

Important for you: This C1 rule no longer affects you today. Anyone submitting an application now needs B1.

What you actually need today (Status 2026)

Standard naturalization (technical term: naturalization by right under § 10 StAG) has these core requirements:

1. Typically 5 years of lawful residence in Germany (uniformly for all since October 30, 2025).
2. An appropriate residence permit.
3. German at B1 level.
4. Passing the naturalization test (“Life in Germany”).
5. Your livelihood is secured, meaning no unemployment benefits (Bürgergeld) from the job center (housing benefit, child allowance, or BAföG are usually not an obstacle).
6. Commitment to the free democratic order and no relevant criminal convictions.

Language is therefore just one of several points. But it’s the one you can best control yourself.

How to prove B1

You must demonstrate B1 with a recognized certificate. The most common ways:

Via the integration course (DTZ)

If you attend an integration course, you take the Deutsch-Test für Zuwanderer (DTZ) at the end. This is a single exam with two possible results: A2 or B1. There is a written section (listening, reading, writing, approximately 100 minutes) and a spoken section (approximately 15 to 20 minutes). Your overall level is based on your points. For naturalization, you must achieve B1.

Via a separate certificate (telc B1 or Goethe B1)

You can also prove B1 independently of the integration course, for example with telc Deutsch B1 or the Goethe Certificate B1.

The Goethe Certificate B1 consists of four modules: reading, listening, writing, and speaking. Each module is worth a maximum of 100 points; a module is passed with 60 points (60%). An advantage: you can retake individual modules separately if you fail one. You don’t have to retake the entire exam.

How to prepare for B1

B1 means: you can talk about everyday topics, write simple letters and messages, have conversations, and understand texts that come up in your life in Germany. This is achievable, even if you work or have a family.

A few practical tips:

• Learn systematically from A1 through A2 to B1. Those who skip gaps often fail at writing and speaking.
• Practice speaking specifically. In the DTZ and the Goethe exam, the spoken portion is decisive.
• Do practice exams. This way you know the format before exam day.

If you want to learn flexibly from home, a structured online course is a good option. Our B1 course takes you to B1 level with real video lessons from an accredited German-as-a-foreign-language teacher and the Hueber textbook “Schritte plus Neu,” with preparation for telc, Goethe, and DTZ. If you’re not quite there yet, it’s best to start with the complete package A1 through B1 and build step by step.

Conclusion

Don’t let rumors about C1 unsettle you. For naturalization, B1 is enough. The C1 path through faster naturalization has not existed since October 30, 2025. Focus on a solid B1 certificate, the naturalization test, and a secure livelihood, then you’re on the right path to a German passport.
