Route Map
Choose Naturalisation Only After Checking Whether Citizenship Already Exists
Separate naturalisation from existing citizenship, family routes, declaration, and restitution before choosing a statute.
Start with the legal outcome, not an application form. Naturalisation, or Einbürgerung, grants German citizenship to a person who is not already German. Citizenship by descent, birth in Germany, adoption, declaration, and restitution for National Socialist persecution are different routes. A person who may already be German should first seek nationality confirmation or the relevant passport and civil-status procedure; paying for a naturalisation test would solve the wrong problem.
Compare the resident routes
| Situation | Likely starting route | Main timing question |
|---|---|---|
| Long-term resident | Section 10 entitlement naturalisation | Have five years of lawful habitual residence been completed? |
| Spouse or registered partner of a German | Section 9 route | Have residence reached three years and the relationship two years? |
| Family applying together | Main applicant plus co-naturalisation | Which spouse, partner, or minor child may use a shortened residence period? |
| Person outside the entitlement conditions | Discretionary naturalisation | Is there a public interest and can the authority lawfully exercise discretion? |
| German parent, German birth rule, persecution history, or earlier loss | Descent, birth, declaration, restitution, or confirmation | Is the person already German or entitled under a separate statutory route? |
The current Section 10 route ordinarily uses five years of lawful habitual residence. It is not enough merely to be registered at an address for five calendar years. The authority separately checks legal status, identity and nationality, livelihood, German, civic knowledge, constitutional commitments, and criminal history.
For a spouse or registered partner of a German, Section 9 normally uses three years of lawful habitual residence plus two years of marriage or registered partnership, with the core Section 10 requirements still applying. A public-interest reduction may exist after a three-year relationship, but it is not an automatic shortcut. The relationship must still be intact at naturalisation.
German law now allows multiple citizenship after naturalisation. That does not bind another country. Before filing, obtain written or official consular guidance on whether acquiring German citizenship automatically ends, suspends, or affects your existing nationality, property rights, military duties, or ability to pass citizenship to children.
Use federal law to select the route, then use the nationality authority for your main residence to confirm its checklist and channel. A Land or municipality may control forms, appointments, digital submission, and document recency, but cannot invent a different federal residence period. For most eligible residents, start with Section 10; for a German spouse, compare Section 9; for a possible existing or restored nationality, pause naturalisation and investigate that route first.
Eligibility
Test Residence, Status, Identity, Livelihood, Language, Civic Knowledge, and Conduct Separately
Audit every statutory condition instead of treating five years at a registered address as sufficient.
Treat eligibility as a series of gates. Passing the five-year residence gate does not cure a non-qualifying title, unresolved identity, missing language proof, or an undisclosed criminal proceeding. Make a one-page table with one row per legal condition and attach the evidence beside it.
Audit lawful habitual residence and present status
The ordinary entitlement route in Section 10 of the Nationality Act requires five years of lawful habitual residence. Short holidays normally do not interrupt the period. Time on a Duldung does not count. Time in an asylum procedure counts under the federal guidance only if the person was later recognised as entitled to asylum, as a refugee, or as a beneficiary of subsidiary protection. Registration records help prove where you lived, but residence permits, EU free-movement evidence, and entry and absence records prove why the stay was lawful.
EU and EEA citizens should document free-movement status rather than searching for a residence permit they were not required to hold. Third-country nationals must hold an eligible current status; Section 10 excludes specified temporary purposes, including several study, training, job-search, temporary-protection, and humanitarian titles. A worker, Blue Card holder, family resident, self-employed person, or permanent resident should match the exact section printed or encoded on the current document. Ask the nationality authority in writing if the title is ambiguous before ordering expensive foreign records.
Check the personal conditions
Identity and nationality must be clarified through reliable documents or, where normal records genuinely cannot be obtained, a documented alternative evidence chain. The applicant must make the required constitutional commitments and must not pursue disqualifying anti-constitutional activity. Antisemitic, racist, or other conduct showing contempt for human dignity is incompatible with naturalisation.
The normal language level is B1. German school qualifications, an eligible German degree, or integration-course evidence may prove it. Different rules exist for children under 16, certain historic guest and contract workers and spouses who joined them, and people unable to meet the ordinary rule because of age, illness, disability, or demonstrated hardship. Civic knowledge is normally shown through the naturalisation test or Life in Germany test, with education and medical exceptions assessed under current rules.
Livelihood ordinarily means supporting yourself and dependent family without Bürgergeld or social assistance. Statutory exceptions include qualifying former guest or contract workers through no fault of their own, a person working full-time for at least 20 of the prior 24 months, and a qualifying spouse or partner living with that worker and a minor child. Other hardship or discretionary cases, including disability, illness, care, single parenthood, or a low pension after work, require individual assessment. Declare benefits and ask for the exact exception; never omit them.
Documents
Build a Route-Specific File and Reconcile Every Name, Date, Address, and Status
Match identity, family, residence, income, language, test, and conduct evidence to the exact route.
Request the local checklist before collecting documents because accepted age, format, and submission method vary. Keep an indexed working copy and a separate set of originals. Do not email unredacted passports, tax records, or criminal records to an unofficial address; use the authority's portal, secure upload, post, or appointment channel.
Prove identity, nationality, family, and residence
Start with the current passport or recognised travel document, previous passports covering the residence period, birth certificate, and evidence of current and former nationalities. Add marriage, partnership, divorce, death, adoption, custody, and children's birth records when the route or family application depends on them. If a name or date differs, obtain a civil-registry correction, name-change record, transliteration explanation, or other official link before filing.
Create a residence chronology with entry dates, every residence title or EU status basis, Anmeldung history, and absences. Pair each registration period with the legal document that covered it. Keep travel records and a written explanation for long trips or gaps. An expired passport may still be useful history, but the current passport and immigration document must remain valid while the case is pending.
Prove livelihood, language, knowledge, and conduct
Employees should expect contracts, recent payslips, employer confirmation, tax assessments, health insurance, and household-cost evidence. Self-employed applicants may need tax returns and assessments, current profit evidence, business registration or professional records, insurance, and pension planning. Pensioners, benefit recipients, carers, and spouses relying on a statutory exception should submit the decision letters and facts establishing the exception rather than hiding the payment.
Use the exact B1 certificate or accepted German education record requested locally. Add the naturalisation-test or Life in Germany result unless an exemption applies, and document the exemption with the issuing school, university, doctor, or other competent body. Disclose German and foreign convictions and pending investigations accurately. The authority checks official registers; concealment is more damaging than a minor matter that may be disregarded.
Foreign public documents may require an apostille or legalisation and a translation by a translator accepted in Germany. For covered documents issued in another EU state, EU authenticity rules remove the apostille and may allow a multilingual form, but they do not determine the document's legal effect. Ask whether the authority needs an original, certified copy, recent issue, or translation and whether it retains or returns it. Before submission, compare spelling, birth data, parents, relationship dates, addresses, title dates, employment, income, and absences across every form and attachment.
Application Steps
Pre-Check the Route, File Through the Local Authority, and Track Every Change
Use the responsible local channel, retain the Aktenzeichen, and keep the file current until certificate handover.
The competent nationality authority is determined by the main residence. It may sit in the city administration, district administration, borough office, or another Land body. The federal naturalisation portal recommends asking the town, district, borough, foreigners authority, or migration advice centre when responsibility is unclear.
Complete the procedure in order
- Classify the route. Check possible existing citizenship, then identify Section 10, Section 9, family co-naturalisation, discretionary naturalisation, or a separate declaration or restitution route. Record why the chosen statute applies.
- Ask for the current local checklist. Confirm the form, online portal or appointment route, accepted translations, document recency, fee method, and whether an initial consultation is offered. Save the dated answer.
- Reconcile prerequisites. Build the residence timeline, renew expiring passport and residence documents, resolve civil-record differences, obtain B1 and civic evidence, and clarify benefit, tax, or criminal-history questions.
- Prepare one consistent application. Answer every question, include foreign proceedings and nationalities, label evidence, and retain a complete copy. A person aged 16 or older normally applies personally; a legal representative applies for a younger child. A lawyer may assist, but cannot make facts true or guarantee priority.
- Submit through the accepted channel. Some authorities accept online applications; others require post or an appointment. Save the submission receipt, timestamp, payment record, and Aktenzeichen. Do not pay a social-media intermediary for a supposedly guaranteed slot.
- Respond and update. Meet evidence deadlines and report a new address, surname, marriage, separation, child, job, income, benefit, criminal investigation, nationality, passport, or residence status. Submit changes under the file reference and keep delivery proof.
- Attend any required appointment and certificate event. Complete identity checks and the statutory declarations. Naturalisation becomes effective only when the authority hands over the certificate after the solemn declaration required by Section 16. Check every personal detail before leaving.
After handover, apply for a German identity card and, if needed, passport through the local identity-document authority. Ask how the residents' register and other public records are updated. Notify employers, banks, insurers, schools, professional bodies, electoral services, and foreign authorities only where nationality or document details matter. Retain the naturalisation certificate permanently; do not surrender the only original to a private organisation.
Costs and Timing
Budget the Fixed Fee, Evidence Costs, and an Officially Long Processing Period
Plan for the EUR 255 fee, tests and records, post-approval documents, and at least the official 18-month estimate.
As checked on 25 August 2026, the federal naturalisation portal states a fee of EUR 255 per person. A minor child without income who is naturalised together with a parent normally costs EUR 51. The naturalisation test costs EUR 25. If payment is difficult, ask the authority before the due date whether a reduction or instalments are available; do not assume a waiver or simply leave an invoice unpaid.
Price the evidence, not only the application
Language-course and B1-exam prices depend on the provider, course intensity, retake, and region. Compare the recognised test provider's current booking page and confirm that the certificate is accepted before paying. German school, university, integration-course, or Life in Germany evidence may avoid a separate test when it satisfies the rule.
Add civil certificates, foreign criminal or status records if requested, certified copies, photographs, postage, and travel. Apostille, consular legalisation, and translation charges depend on the issuing country, page count, language, urgency, and translator. Obtain an itemised quote after the authority confirms what is required. Covered EU public documents may avoid an apostille and sometimes a translation through a multilingual standard form. Advice from a migration counselling centre may be free; lawyer fees are optional unless a complex dispute or court case makes representation proportionate. No private service can lawfully sell approval.
After naturalisation, budget the separately published local fee for the German identity card and passport you actually need. Those document tariffs and delivery options can change, so use the issuing authority's live fee page on the booking date rather than a copied nationwide total. Keep naturalisation, test, evidence, travel, advice, and post-approval document costs as separate budget lines.
Plan for evidence expiry and processing
The same official portal tells applicants to expect 18 months or longer after a complete filing. That is planning guidance, not a guaranteed service target or a legal permission to let immigration documents expire. A complex identity history, foreign verification, security checks, family filing, criminal proceeding, address move, or missing evidence can add time.
Work backward from the eligibility date: request foreign civil records and resolve identity issues first; book language or civic tests early; ask the local authority when it wants recent payslips, tax assessments, and certificates; then file when every current condition can be proved. Avoid ordering short-validity records so early that they expire before submission. Continue saving updated payslips, tax records, passports, residence documents, and correspondence throughout the pending period.
Pending and After Approval
Keep Immigration Status Valid Until Citizenship Begins, Then Replace Identity Documents
Maintain valid immigration documents while pending and treat certificate handover as the legal completion point.
A naturalisation application is not a residence-title application. It does not itself extend a visa, residence permit, EU right, passport, or travel document. The official naturalisation guidance expressly tells pending applicants to renew passports and residence documents. Keep meeting the conditions of the existing immigration status and file any necessary renewal with the responsible foreigners authority on time. Preserve that separate receipt.
Maintain a live case file
Record the application date, payment, submission receipt, Aktenzeichen, caseworker, every evidence request, response deadline, delivery proof, and the version of each document supplied. Report changes in address, name, family, employment, benefits, criminal proceedings, passport, nationality, or residence status promptly. A move can transfer responsibility to a new nationality authority; ask both authorities how the file and outstanding deadline will be handled.
The five-year condition must be satisfied under the applicable law and facts, but the authority also assesses the current conditions before grant. Job loss, separation from a German spouse, departure from Germany, or a new benefit claim can therefore matter after submission. Do not guess that the filing freezes eligibility. Send the change with a short explanation and evidence, and ask which route or exception remains available.
Identify the legal completion point
An encouraging letter, fee request, appointment invitation, or approval notice is not yet German citizenship. Under Section 16 of the Nationality Act, naturalisation becomes effective when the nationality authority hands over the naturalisation certificate, after the required solemn declaration. Verify the name, birth details, and other entries immediately and request correction before the error spreads into identity documents.
After handover, book the German identity card and passport routes appropriate to your travel and residence. Ask the residents' registration office whether nationality updates automatically. Update payroll, bank know-your-customer data, insurance, pension, professional licences, university or school records, and any benefit file where the new nationality changes evidence. Check the prior country's rules and complete any required notification there. Preserve the certificate in secure storage and use certified copies where accepted.
Backward planning is simple: keep current status valid; maintain fresh evidence; respond before every stated deadline; plan for at least the official 18-month estimate; and do not make irreversible nationality, travel, employment, or relocation decisions until the certificate has been handed over and the consequences in every other country are known.
Problems and Remedies
Repair the Evidence, Preserve Deadlines, and Challenge the Exact Reason
Turn identity, residence, livelihood, criminal-record, delay, and refusal issues into evidence-backed disputes.
When a case stalls, separate a missing-document problem from a disputed legal condition. Ask for the exact outstanding item, statutory issue, response date, and accepted substitute in writing. Reply under the Aktenzeichen and preserve portal receipts, postal tracking, emails, call notes, fee records, and copies of everything submitted.
Fix common blockers at their source
For unclear identity or nationality, prepare a documented search trail: requests to registries and consulates, negative replies, family and school records, earlier passports, witness or expert evidence where accepted, and an explanation of spelling or date differences. For a residence gap, pair registration history with residence titles, EU-status evidence, travel records, and authority correspondence. For livelihood concerns, identify the exact benefit and show earnings, household composition, full-time work history, care duties, disability, illness, pension history, or the statutory exception relied on.
Disclose criminal matters. Under Section 12a, fines up to 90 daily rates and certain suspended prison sentences up to three months can ordinarily be disregarded, but multiple sentences are aggregated and antisemitic, racist, or other contempt-for-human-dignity motives are treated differently. A pending investigation pauses the decision, and foreign convictions and proceedings must be stated. Obtain the judgment and qualified advice rather than estimating from memory.
If another country may withdraw your nationality, pause any irreversible step and obtain official foreign-law guidance. Germany allowing multiple citizenship does not prevent that consequence. Treat anyone selling guaranteed dual nationality, a priority appointment, or approval as a scam risk; verify payment instructions on the authority's own site.
Escalate delay or refusal proportionately
For silence, first confirm that the authority received a complete application and ask for a status update and any missing item. Free migration counselling can help organise the file. A lawyer specialising in nationality and administrative law becomes proportionate where identity evidence is rejected, residence or title counting is disputed, criminal history is complex, the route changed while pending, a formal refusal arrives, or delay is extreme.
Read the decision's Rechtsbehelfsbelehrung immediately. It controls whether an administrative objection is available or the case goes directly to the administrative court, and it states the deadline and competent body. Do not assume every Land uses the same objection stage. Preserve the envelope or electronic-service timestamp, request the authority's calculation and file access where appropriate, and challenge the exact finding with primary evidence. If the defect is curable and no deadline is endangered, a corrected or later application may be cheaper than litigation; compare both routes before paying.
