telc B1 for German Citizenship: The Current Rules (2026)
Last updated: August 2026 · 7 min read
For German naturalisation (Einbürgerung) under §10 StAG, the required language level is B1, and telc Deutsch B1 satisfies it — it is accepted by immigration authorities across Germany. Two details deserve attention, though: the all-four-skills rule and the residence period that changed in 2025.
This article is general information, not legal advice. For the specifics of your application, speak to your own Einbürgerungsbehörde; practice can differ between federal states and districts.
Which certificates are accepted?
For "sufficient knowledge of German" under §10 StAG, the following are accepted in particular:
- telc Deutsch B1
- Goethe-Zertifikat B1
- ÖSD Zertifikat B1
- Deutsch-Test für Zuwanderer (DTZ) with a B1 result
Higher levels (B2, C1, C2) count a fortiori. In administrative practice, a German general school-leaving certificate also satisfies the requirement.
The critical point: all four skills
In administrative practice, a "B1 certificate" means one covering all four skills — Hören, Lesen, Schreiben, Sprechen. A purely written or purely oral partial exam is normally not enough.
For candidates choosing telc this is actually an advantage: telc Deutsch B1 is not modular, so passing it already evidences all four skills at once. With modular exams such as Goethe or ÖSD you can take modules one at a time — and then you must complete all four; a missing module leaves you with a certificate that is not sufficient for citizenship.
Residence period: the three-year track is gone
Citizenship law changed twice in two years, and a great deal of online content still describes the old position. The current picture:
| Date | Change |
|---|---|
| 27 June 2024 | The new citizenship act (StARModG) came into force: the general residence requirement fell from eight years to five, a three-year fast track was introduced for "special integration achievements", and dual citizenship became available to everyone. |
| 30 October 2025 | The three-year fast track was abolished. Since then the general minimum is again five years' residence, and the rule applies to applications that were already pending. |
The language requirement was untouched by these changes: §10 StAG requires level B1. (The abolished three-year route asked for a higher language level; that route no longer exists.)
Exceptions
For the so-called guest-worker generation (Gastarbeitergeneration) the law introduced a specific relief: for this group proof of oral language skills is sufficient and no Einbürgerungstest is required. Exceptions also exist for people who cannot meet the language requirement because of illness, disability or age — these are assessed individually, on documentary evidence.
Does the certificate expire?
A telc Deutsch B1 certificate carries no expiry date. That said, some authorities may ask for a current confirmation of your level if the certificate is very old — that is administrative discretion, not invalidity of the certificate. Asking the office handling your application is the safest route.
A practical route
- Check the residence period — the current rule is five years.
- Get the B1 certificate. telc Deutsch B1 covers all four skills in a single exam; passing requires 135 written and 45 oral points.
- Sit the Einbürgerungstest (unless an exception applies to you).
- File the application with the supporting documents your office requires (income, identity, criminal record).

Conclusion
On the language side the answer is simple: B1 is enough, and telc Deutsch B1 is accepted, evidencing all four skills in one exam. The point that really needs attention is not the language but the timeline: since 30 October 2025 the minimum residence period is five years, and the three-year fast track no longer exists.
