Last updated: August 2026
The general route to German citizenship through naturalization usually requires at least five years of lawful habitual residence in Germany.
Five years alone is not enough.
The naturalization authority also examines other requirements, which can include:
your residence history
your current residence status
German language ability
knowledge of Germany’s legal and social system
financial self-sufficiency
identity and nationality
criminal convictions
commitment to Germany’s constitutional order
Germany generally permits multiple citizenship. However, whether you retain your previous citizenship also depends on the law of the country or countries whose citizenship you already hold.
This guide explains the main published requirements for ordinary naturalization after living in Germany.
It does not cover every citizenship route or determine whether an individual applicant qualifies.
What this guide covers
This article focuses on ordinary naturalization after a period of residence in Germany.
Different rules can apply to German citizenship through:
descent
a German parent
adoption
declaration
restoration
historical persecution
former German citizenship
special family situations
These routes can involve complex nationality-law questions.
Marriage to a German citizen can also affect the applicable naturalization rules, but it does not automatically make someone German.
For questions about citizenship by descent, restoration or another special route, consult the responsible authority or a licensed German lawyer specializing in nationality law.
The direct answer
To understand how to become a German citizen through ordinary naturalization, begin with the following general requirements:
You have usually lived lawfully and habitually in Germany for at least five years.
You hold a residence status suitable for naturalization.
Your identity and nationality are clarified.
You generally have German at B1 level.
You meet the knowledge requirement, often through the naturalization test.
You can generally support yourself and eligible dependents.
You have no disqualifying criminal convictions.
You make the required declarations and commitment to Germany’s constitutional order.
The authority examines the complete application and individual circumstances.
Five years is the general residence period
The general statutory residence period for ordinary naturalization is five years.
The previous option to naturalize after three years based on exceptional integration achievements was abolished in October 2025.
That route is no longer available.
The five-year period is a minimum threshold. It does not mean that German citizenship is granted automatically after the fifth anniversary of your arrival.
You must submit an application and meet the other legal requirements.
The authority then reviews:
whether your residence was lawful
whether it was habitual
whether the relevant periods count
whether there were interruptions
whether long absences affect the calculation
whether your current status supports naturalization
Which residence periods count?
Residence history can be more complicated than simply counting calendar years.
Relevant factors can include:
the type of residence status held
periods under different residence permits
previous asylum or protection procedures
temporary residence documents
study periods
time spent outside Germany
interruptions in registration
the purpose of residence
the date from which habitual residence is recognized
Not every period or status is necessarily treated in the same way.
Do not assume that every day spent physically in Germany automatically counts toward the five-year period.
If your residence history includes long absences, temporary statuses, asylum proceedings or interruptions, ask the naturalization authority or a licensed lawyer to assess it.
Do you need a particular residence permit?
The authority examines your residence status at the time of naturalization.
A temporary residence permit does not automatically prevent naturalization. However, some statuses may not provide the required long-term residence perspective.
The correct assessment can depend on:
the legal basis of the residence permit
the intended duration
the purpose of stay
whether the status can lead to longer-term residence
your personal circumstances
An EU Blue Card is not required.
People can potentially qualify through different residence histories, including employment, family or other qualifying routes.
A settlement permit can make the long-term perspective clearer, but it is not always a mandatory preliminary step.
Do not rely on a general article to determine whether your exact residence title is sufficient.
German language requirements
B1 German is generally required for ordinary naturalization.
You may be able to demonstrate this through documents such as:
a recognized German language certificate
a German school certificate
a German vocational qualification
a German university degree
another accepted educational record
The authority decides which evidence it accepts.
Different or reduced requirements can apply in specific statutory situations, including certain cases involving:
age
illness
disability
hardship
members of the former guest-worker or contract-worker generation
These exceptions should not be assumed without confirmation.
If you are unsure whether your certificate or personal situation meets the requirement, ask the responsible authority.
Naturalization test and knowledge requirements
Applicants generally need to demonstrate knowledge of:
Germany’s legal system
social conditions
democratic institutions
history
civic responsibilities
This is commonly done through the naturalization test.
The test includes questions about:
democracy
constitutional rights
federal and state institutions
elections
German history
society
everyday civic life
Certain school or educational qualifications may provide an alternative form of evidence.
Exceptions can also apply in specific situations.
The authority decides whether you need to take the test and which documents satisfy the requirement.
Financial self-sufficiency
Applicants generally need to be able to support themselves and eligible dependents without relying on certain means-tested public benefits.
The assessment can involve:
employment income
self-employment income
household income
family circumstances
housing costs
maintenance obligations
current benefit receipt
reasons for unemployment or reduced income
statutory exceptions
The rule is not as simple as checking one fixed income figure.
The law contains exceptions, and authorities must consider the individual circumstances.
Do not use an online calculator or general article as a binding assessment of financial eligibility.
If your situation includes unemployment, illness, parental leave, disability, social benefits or irregular income, obtain guidance from the naturalization authority or a lawyer.
Identity and nationality
Your identity and current nationality must generally be clarified.
The authority may ask for documents such as:
passport
national identity card
birth certificate
marriage certificate
civil-status records
previous passports
nationality certificates
name-change documents
The required documents depend on your country and personal history.
Difficulties can arise when:
documents are unavailable
records contain different spellings
dates are inconsistent
a country does not issue certain certificates
identity documents have expired
the person is stateless
nationality is disputed
These cases require individual assessment.
Do not submit altered, incomplete or inconsistent documents.
Criminal convictions
Criminal convictions can affect naturalization.
The outcome can depend on:
type of offense
sentence
number of convictions
age at the time
whether proceedings are still pending
whether the offense falls within a statutory disregard rule
whether the conduct raises constitutional concerns
Not every minor offense automatically prevents naturalization.
Serious or repeated convictions can create major obstacles.
If you have a conviction, pending criminal case or investigation, consult a licensed lawyer before relying on general information.
Commitment to Germany’s constitutional order
Naturalization requires a commitment to Germany’s free democratic constitutional order.
Applicants must make the declarations required by the current Citizenship Act.
Conduct or statements that are antisemitic, racist or otherwise directed against human dignity can be incompatible with naturalization.
The authority can also examine whether an applicant supports extremist or anti-constitutional activities.
A general blog post cannot determine how a particular statement, association or past activity will be assessed.
Anyone concerned about this part of an application should seek legal advice.
Multiple citizenship
Germany generally permits multiple citizenship.
Applicants are therefore usually not required by German law to give up their existing citizenship when becoming German.
However, this does not guarantee that the country of origin will allow the person to keep its citizenship.
Other countries may:
permit multiple citizenship
require prior approval
limit it to certain cases
withdraw citizenship automatically
require notification
prohibit it entirely
Before naturalizing, check the nationality law of every country whose citizenship you hold.
German authorities can explain the German side of the process. For the foreign-law consequences, consult the relevant embassy, consulate or qualified lawyer.
Does marriage to a German citizen grant citizenship?
No.
Marriage to a German citizen does not automatically make the foreign spouse German.
Special naturalization rules can apply to spouses or registered partners of German citizens.
These rules can involve:
a shorter residence period
a minimum duration of the marriage or partnership
the continuation of the marital relationship
the ordinary naturalization requirements
additional individual circumstances
The exact requirements must be assessed by the naturalization authority.
Do not confuse marriage-based residence rights with citizenship.
A residence permit through marriage and German nationality are separate legal matters.
Children born in Germany
A child born in Germany to foreign parents can acquire German citizenship at birth if at least one parent meets the statutory requirements.
These generally include:
a minimum period of lawful habitual residence in Germany
a qualifying residence status
The residence period was reduced from eight to five years through the 2024 citizenship reform.
The exact result depends on the parents’ status at the time of birth.
A birth in Germany alone does not always create German citizenship.
Parents should check the registration and nationality documents issued after the birth and ask the competent registry or nationality authority if anything is unclear.
Children included in a parent’s application
Minor children can sometimes be naturalized together with a parent even if they have not personally completed the full general residence period.
The authority examines factors such as:
age
custody
residence
language development
family situation
the parent’s application
Do not assume that a child is automatically included.
Each child should be listed and documented according to the authority’s instructions.
How to apply for naturalization
The application process differs between German cities, districts and federal states.
The responsible office may be called:
naturalization authority
nationality authority
citizenship office
district administration
city administration
immigration or integration authority
Some authorities offer a complete online application. Others use:
online pre-checks
downloadable forms
email
postal applications
appointments
a combination of methods
Step 1: Identify the responsible authority
The competent authority is generally based on your registered address.
Use the website of your city, district or federal state to find the correct procedure.
Do not send the application to another authority because it appears to have shorter processing times.
Step 2: Read the local requirements
Local websites can differ in:
application format
document list
translation rules
certification requirements
accepted language certificates
fee payment
appointment process
Follow the instructions of the authority handling your application.
Step 3: Prepare the documents
Commonly requested documents can include:
passport
current residence permit
birth certificate
civil-status documents
proof of residence history
language certificate
naturalization test certificate
employment contract
salary records
tax documents
health insurance evidence
rental agreement
proof of household income
documents for spouse and children
declarations required by the authority
This is not a complete universal checklist.
The authority may request additional documents based on your history and circumstances.
Step 4: Submit the application
Submit the application through the official method specified by the authority.
Keep evidence showing:
submission date
reference number
documents submitted
payment
later correspondence
Do not send duplicate applications through several channels unless the authority instructs you to do so.
Step 5: Respond to requests
The authority may request:
updated income records
new identity documents
missing translations
clarification of residence periods
additional civil-status records
security declarations
information about criminal proceedings
documents from foreign authorities
Respond within the stated deadline.
Notify the authority of important changes, such as:
new address
new employer
unemployment
marriage
divorce
birth of a child
extended travel abroad
criminal proceedings
change of citizenship
Step 6: Wait for the decision
The authority checks the legal requirements and may consult other public bodies.
A successful decision results in naturalization.
You become German when the naturalization certificate is formally handed over, not merely when the application is approved internally.
Follow the authority’s instructions about the ceremony or collection appointment.
Step 7: Apply for German identity documents
After receiving the naturalization certificate, you can apply for:
a German identity card
a German passport
These are separate applications.
The naturalization authority does not normally issue the passport itself.
How long does naturalization take?
There is no single nationwide processing time.
The procedure can vary considerably depending on:
city or district
authority workload
completeness of documents
residence history
identity verification
foreign civil-status records
security checks
family applications
legal complexity
Do not assume that another person’s processing time will apply to you.
Check the information published by your local authority.
Avoid booking non-refundable travel based on an expected naturalization date.
How much does naturalization cost?
The standard fee is generally set by law.
Additional costs can arise for:
language tests
naturalization test
translations
certified copies
foreign civil-status documents
passport
identity card
legal assistance
Fees can differ for children included with a parent and in other specific situations.
Check the current fee information from the responsible authority before applying.
Can citizenship be withdrawn after naturalization?
A naturalization obtained through fraud, threats, bribery or deliberately false or incomplete information can be withdrawn under the statutory conditions.
This is not the same as simply canceling a German passport.
The issue concerns whether citizenship was obtained unlawfully.
Always provide complete and accurate information.
If you discover a serious mistake in a submitted application, obtain legal advice rather than trying to conceal it.
Common misunderstandings
“I automatically become German after five years”
No. Five years is the general minimum residence period. You must apply and meet the other requirements.
“The three-year fast-track route still exists”
No. It was abolished in October 2025.
“I apply directly for a German passport”
No. First you apply for naturalization. You can apply for a passport after becoming German.
“Marriage to a German automatically gives me citizenship”
No. Marriage can affect the applicable rules but does not create citizenship automatically.
“A German residence permit automatically leads to citizenship”
No. Residence status is only one part of the assessment.
“An EU Blue Card guarantees naturalization”
No. It can support a long-term residence path but does not guarantee citizenship.
“Germany allows multiple citizenship, so I will definitely keep my old citizenship”
No. The law of the other country also matters.
“Every period spent in Germany counts”
Not necessarily. The authority examines the legal and habitual residence history.
“B1 German is the only requirement”
No. Language is only one of several requirements.
“A minor conviction never matters”
Criminal-law consequences depend on the offense and statutory rules.
“A child born in Germany is always German”
No. The statutory parental residence and status requirements must be met.
When should you consult a lawyer?
Seek legal advice if your case involves:
uncertain residence periods
long absences from Germany
asylum or temporary protection histories
unclear identity or nationality
missing civil-status documents
criminal convictions
pending criminal proceedings
extremist allegations
social-benefit questions
possible loss of another citizenship
a rejected naturalization application
withdrawal of a previous naturalization
citizenship by descent or restoration
complex family situations
A licensed German lawyer can assess the law and individual facts.
