German Citizenship: Naturalisation Guide for Expats

German citizenship by naturalisation requires five years of lawful residence, B1 German, the Einbürgerungstest — and since 2024, dual citizenship is allowed in most cases without giving up your original passport.

12 min read·Verified & sourced

Overview

Naturalisation (Einbürgerung) grants German citizenship and a German passport. Since the nationality law reform of June 2024 (StARAG), the standard path is five years of lawful residence — down from eight — and dual citizenship is generally allowed.

Details
Legal basis§10 StAG (Staatsangehörigkeitsgesetz)
Standard residence5 years lawful habitual residence
LanguageB1 German
Integration testEinbürgerungstest (17/33 correct)
Fee€255 adult / €51 minor child
Dual citizenshipGenerally permitted since 2024 reform
EntitlementLegal right if requirements met — not discretionary

This is the final milestone on the staying long-term path. Most applicants obtain permanent residence first, then apply for citizenship.

Note: A three-year fast track for special integration existed briefly in 2024–2025 and was abolished in late 2025. The standard path is five years for everyone unless you qualify for a special route (e.g. marriage to a German citizen).

Who can apply (§10 StAG)

RequirementDetails
5 years residenceLawful, habitual residence in Germany — continuous
IdentityPassport and nationality established
Residence permitValid secure status — ideally Niederlassungserlaubnis
LivelihoodSelf-support without Bürgergeld or Sozialhilfe
LanguageB1 German
IntegrationEinbürgerungstest or equivalent
Criminal recordNo convictions above certain thresholds
Constitutional orderCommitment to free democratic basic order (Grundgesetz)

If all boxes are checked, you have a legal entitlement to naturalisation — authorities must grant it unless an exception applies.

What counts toward the five years

Time on this statusUsually counts?
EU Blue CardYes
Skilled worker permitYes
Family reunion permitYes
Permanent residenceYes
Student visaUsually no — check partial credit rules
Language course / job-seeker onlyUsually no
Duldung (tolerated stay)No
Gaps without valid permitBreak continuity — clock may reset

Absences: Trips abroad under six months generally do not break habitual residence. Longer absences need Ausländerbehörde approval or the five-year period may restart.

Keep every Meldebescheinigung, permit card, and Anmeldung confirmation from day one.

Dual citizenship (2024 reform)

Before 2024, most applicants had to renounce their original nationality. That has changed.

SituationTypical outcome
Naturalisation under current §10 StAGKeep both passports in most cases
Your home country allows dual nationalityNo conflict
Your home country forbids dual nationalityCheck home-country law — Germany no longer forces renunciation in most cases

EU countries, US, UK, and many others accept dual citizenship with Germany. Some countries (e.g. India, Japan) still restrict dual nationality on their side — consult your embassy.

Special routes

Language and integration test

B1 German

Higher bar than family reunion A1. Accepted proof:

  • Goethe-Zertifikat B1 or telc Deutsch B1
  • DTZ (Deutsch-Test für Zuwanderer) after integration course
  • German Abitur or equivalent school-leaving certificate

PrepSame material as Leben in Deutschland for settlement

If you already passed for Niederlassungserlaubnis, submit the same certificate.

Secured livelihood

You must support yourself and dependants without relying on:

  • Bürgergeld (citizen's allowance)
  • Sozialhilfe (social welfare)

Accepted: Employment income, self-employment profits, spouse's income, savings.

Grey area: Short ALG I during job search is not the same as long-term welfare — document the period and confirm with the Einbürgerungsbehörde.

Receiving Kindergeld or child benefits does not block naturalisation — it is not means-tested welfare.

The authority is often the Einbürgerungsbehörde at your Land level — in some cities merged with the Ausländerbehörde. Use the federal Quick-Check tool linked from BMI citizenship pages before applying.

Step-by-step process

  1. Track five-year clock

    From first qualifying lawful residence — avoid long illegal gaps

  2. Obtain Niederlassungserlaubnis

    Often before or alongside citizenship prep — see PR guide

  3. Pass B1 + Einbürgerungstest

    12–18 months before earliest application date

  4. Gather residence and income proof

    Anmeldung history, Steuerbescheid, employment records

  5. Submit naturalisation application

    To local Einbürgerungsbehörde (often via Ausländerbehörde portal)

  6. Decision and certificate

    Often 12–24 months processing — legal entitlement if requirements met

1. Confirm eligibility date

Mark five years from your first qualifying permit — not your first tourist visit. If you had student years, ask whether any time counts at a discount.

2. Secure permanent residence (recommended)

Not always legally mandatory before citizenship, but Niederlassungserlaubnis proves long-term integration and removes employment conditions from your status.

Blue Card holders can reach PR in 21–27 months — then count remaining years toward citizenship.

3. Pass B1 and Einbürgerungstest

Book exams 12–18 months before your earliest application date. Integration courses (Integrationskurs) combine language and civics prep.

4. Collect residence history

  • All Aufenthaltstitel cards (even expired)
  • Meldebescheinigung from every address
  • Steuerbescheid (tax assessments) for income proof
  • Pension records if relevant

5. Submit application

Apply to your local Einbürgerungsbehörde with forms, declarations, and fee (€255). Some federal states use online portals.

Processing: often 12–24 months. If requirements are met and no decision arrives within six months in some cases, legal remedies may apply — consult a lawyer if stalled.

6. Receive Einbürgerungsurkunde

Attend in person to receive your naturalisation certificate. Apply for a German passport at the Bürgeramt — your first EU passport.

After naturalisation

TopicWhat changes
VotingFull federal and state voting rights
EU freedom of movementLive anywhere in EU/EEA
PassportGerman passport — visa-free travel expands
Kindergeld / benefitsSame as before — citizenship does not reduce entitlements
TaxSame tax system — church tax still applies if registered

You no longer need visa extension or permit renewals.

Common mistakes

  1. Relying on outdated 3-year fast track — Abolished late 2025; plan for five years.
  2. Assuming student years count fully — Often excluded or discounted.
  3. Bürgergeld period on record — Can block naturalisation even after stopping.
  4. Permit gap breaking continuity — Never overstay without valid title.
  5. Wrong test certificate — Einbürgerungstest ≠ driving licence theory test.
  6. Not checking home-country dual citizenship rules — Germany allows dual; your origin country might not.
  7. Applying before five years complete — Application date must be exactly eligible or later.

Frequently asked questions

How long do I need to live in Germany before applying for citizenship?

Under the current Staatsangehörigkeitsrecht (reformed June 2024), you need five years of lawful habitual residence in Germany. A former three-year fast track for special integration achievements was removed in late 2025. Spouses of German citizens may qualify after three years of residence plus two years of marriage under section 9 StAG.

Can I keep my original passport when I become German?

In most cases yes. Since the 2024 nationality law reform, dual citizenship is generally permitted for naturalisation applicants. You no longer need to renounce your previous nationality in the majority of situations — though your home country may have its own rules on dual nationality.

Do I need permanent residence before applying for citizenship?

You need a secure residence status — typically a Niederlassungserlaubnis or another qualifying long-term permit at application time. You can apply once you meet the five-year residence rule if your current title is valid. See our permanent residence guide for the step before citizenship.

What German level is required for naturalisation?

B1 on the CEFR scale — conversational German. Accepted certificates include Goethe-Zertifikat B1, telc Deutsch B1, DTZ after an integration course, or a German school-leaving certificate. The level is higher than the A1 spouse visa requirement for family reunion.

What is the Einbürgerungstest?

A 33-question citizenship test on German law, history, and society. You need 17 correct answers to pass. It costs about €25 and is the same knowledge area as the Leben in Deutschland test used for settlement permits. If you already passed Einbürgerungstest for Niederlassungserlaubnis, you usually do not retake it.

How much does German citizenship cost and how long does it take?

The naturalisation fee is €255 for adults and €51 for each minor child naturalised together (section 38 StAG). Processing often takes 12–24 months depending on city backlog. You have a legal entitlement to naturalisation if all requirements under section 10 StAG are met — not a discretionary favour.
