Five years in Germany, a job and a language certificate: for many people, these are the first points of reference on the path to naturalisation. Whether they give rise to an entitlement, however, depends on how the individual requirements fit together. Earlier periods of residence, the family's financial circumstances or missing documents from the country of origin may require closer examination. This overview explains the connections and shows which evidence and exceptions are important.
When is there an entitlement to naturalisation?
For your application, we assess lawful habitual residence, a suitable residence status, identity and nationality, subsistence, and language and civic knowledge. The statutory declarations of commitment are also required, alongside checks for criminal offences and other grounds for exclusion. Meeting one requirement particularly well does not generally compensate for another. A high income, for example, does not compensate for an identity that has not been established. Statutory concessions must relate to the specific requirement concerned. The legal basis is § 10 StAG.
There are also special routes to naturalisation, for example for spouses of German citizens or through a discretionary decision. The article on naturalisation by entitlement and discretionary naturalisation explains the differences.
Residence: duration and current status are two different questions
Which time in Germany counts?
Naturalisation by entitlement generally requires five years of lawful habitual residence. This means that Germany is the actual centre of a person's life and that their residence is covered by a corresponding right of residence. A registration certificate can document periods at an address, but does not, on its own, establish whether all those periods qualify legally.
The former possibility of reducing this period to three years for special integration achievements was abolished on 30 October 2025. A C1 certificate or exceptional commitment therefore no longer opens up this reduction. The special rules for families that continue to apply must be distinguished from this. The change is explained by the Federal Government in its information on the abolition of the former three-year rule.
Where residence history has involved changes, it is worth creating a timeline: entry, residence titles issued, extensions, periods abroad and return. Study periods may count even though a residence title for study is itself insufficient for subsequent naturalisation. A tolerated stay (Duldung), by contrast, does not make residence lawful. Special rules apply to permission to remain during asylum proceedings (Aufenthaltsgestattung), gaps and longer absences; simply calculating “today's date minus the date of entry” is therefore not always enough.
Which right of residence must be held at the end?
A settlement permit is one possible route, but it is not mandatory. An EU Blue Card and certain temporary residence permits may also qualify. The statutory purpose of residence is decisive. For example, a residence permit for study under § 16b AufenthG is insufficient for naturalisation by entitlement. However, the necessary switch to a suitable title does not automatically mean that study periods which already qualify cease to count.
EU citizens entitled to freedom of movement and other groups have their own legal bases for residence. Residence in Germany explains the connections; the relevant statutory rules are in § 10(1) no. 2 and § 12b of the current consolidated StAG.
Identity and existing citizenship must be established
The authority must be able to establish who is being naturalised and which citizenship that person holds. This requires consistent information, particularly on names, date of birth, place of birth and marital status. We explain different spellings using the available documents. German residence documents already issued do not automatically replace this assessment either.
The tiered model distinguishes five successive levels of evidence:
primarily, a passport;
a recognised passport substitute or another official identity document with a photograph;
other suitable official certificates;
other admissible evidence, particularly non-official documents and witness statements;
exceptionally, the person's own statements following a comprehensive assessment of all the circumstances.
Moving to the next level requires that the preferred evidence cannot be obtained despite sufficient cooperation and that obtaining it is objectively impossible or cannot reasonably be expected of the individual. The sequence determines which evidence may be considered; whether a particular document is convincing is assessed separately.
If a passport is missing, we assess which level of evidence is available: the procedure does not automatically end, but alternative documents cannot simply be chosen at will. What matters is which documents are obtainable, what efforts can reasonably be expected to obtain them and the evidential value of the material available. For recognised refugees, possible dangers arising from contact with the country of origin must be considered individually. Identity and existing citizenship explains the individual routes to providing evidence.
Livelihood: the family's specific circumstances are decisive
There is no single minimum salary
As a rule, applicants must be able to support themselves and their dependent family members without benefits under SGB II or SGB XII. The income needed depends, among other things, on family size, housing costs, health insurance and maintenance obligations. A net salary sufficient for a single person may be too low for a larger family.
Since 1 July 2026, the benefit under § 19 SGB II has been called “Grundsicherungsgeld”. Authorities may continue to use “Bürgergeld” until the end of 2026. This is provided for in § 19 and § 65a(4) SGB II; the Federal Employment Agency's official collection of legislation also contains the record of commencement. For § 10 StAG, classification under SGB II or SGB XII remains decisive, regardless of the name on the benefit decision.
We do not limit our assessment of your subsistence to the latest payslip. It also considers whether financial support is likely to continue. The employment contract, previous employment history or, for self-employed people, informative profit and tax documents may therefore be relevant. A fixed-term contract does not automatically mean rejection; its significance depends on the person's overall employment circumstances.
Not every state payment is a ground for exclusion. Child benefit, parental allowance or insurance benefits are not detrimental simply because a public body pays them. However, their nature, amount and duration must be included in the overall financial assessment. Even someone who does not actually apply for benefits under SGB II or XII must be able to explain how their livelihood is funded.
Which exceptions does the legislation provide?
Caring for a child, illness or losing a job through no fault of one's own does not, on its own, create a general exception under the current version. However, for applications submitted by 23 August 2023, the more favourable earlier rule on securing a livelihood may apply. This is provided for by § 40a StAG. Particular hardship may also require a separate assessment under § 8 StAG. Income and securing a livelihood covers the calculation, exceptions and evidence in more detail.
Provide separate evidence of German language skills and knowledge about Germany
B1 is the standard statutory requirement
German language skills at B1 level are generally required. A recognised language certificate is a usual form of evidence. Depending on the person's education, suitable German-language school, vocational training or university qualifications may also suffice. However, a degree completed in Germany entirely in English does not establish German language skills simply because of where it was obtained.
Concessions have different requirements
For children who are not yet 16 at the time of naturalisation, age-appropriate language development is sufficient. An application submitted before the birthday does not automatically preserve this concession for naturalisation at a later date. For certain former guest workers, contract workers and spouses who joined them, the ability to communicate orally in everyday life without significant difficulty is sufficient; this group does not have to demonstrate civic knowledge.
If the requirements cannot be met because of illness, disability or age, § 10(6) provides for an exemption. However, a diagnosis alone does not answer the question. We check whether the evidence explains how the specific impairment prevents the person from acquiring or demonstrating the required knowledge or skills.
In addition, § 10(4a) allows a hardship concession where achieving B1 is impossible or permanently substantially more difficult despite serious and sustained efforts. Oral communication in everyday life remains necessary in these cases; civic knowledge is waived. This provision must therefore be distinguished from a full exemption on grounds of illness. For more detail, see German language skills and knowledge about Germany.
Declarations of commitment and grounds for exclusion concern a person's actual attitudes
The legislation generally requires a commitment to the free democratic basic order and a declaration concerning activities directed against the constitutional order. It also requires a commitment to Germany's historical responsibility for the injustices of National Socialism, particularly the protection of Jewish life, and to the peaceful coexistence of peoples and the prohibition of wars of aggression.
These declarations are more than a signature. Factual indications that a declaration of commitment is substantively untrue may exclude naturalisation. This also applies to certain extremist activities or acts of support. Where conduct lies in the past, the decisive question may be whether the person can credibly demonstrate that they have turned away from it. § 11 also lists particularly serious grounds for expulsion, being married to several spouses at the same time and conduct that disregards the equality of men and women.
Passing the naturalisation test does not answer these questions: knowledge of the constitution and a personal commitment to it are different requirements. The statutory grounds for exclusion are set out in § 11 StAG, consolidated version; Commitment to the constitution and grounds for exclusion explains how they are assessed.
Criminal offences and ongoing investigations have different consequences
A criminal conviction may prevent naturalisation. However, § 12a StAG disregards certain lesser penalties, generally including fines of up to 90 daily rates. Multiple convictions must not simply be considered individually: the legislation provides rules for adding them together. Where a court has established antisemitic, racist or other motives showing contempt for humanity, the usual exceptions do not apply.
An ongoing investigation is not yet a conviction. However, it generally leads to the naturalisation decision being suspended until the proceedings have concluded; where there is a conviction, it must become final first. Foreign decisions and proceedings can also be relevant and must be disclosed in accordance with the statutory requirements.
Where there is a criminal history, it is therefore insufficient to establish that one's certificate of conduct is clear. What matters includes the specific decision and whether it may legally be taken into account. Criminal offences and ongoing investigations covers the details.
Check separately for an existing bar on naturalisation
Even where the general requirements are met, a ten-year bar on naturalisation under § 35a StAG may prevent it. The legislation distinguishes between the final, unappealable withdrawal of an earlier naturalisation under § 35 and an official finding of certain improper conduct in the naturalisation procedure. For false or incomplete information, it requires intent and a connection to material naturalisation requirements. A typing error, an explainable difference in a name or a change that occurred only later is not automatically equivalent.
The bar, possible criminal liability and the withdrawal of a naturalisation that has already taken effect each have their own requirements. In particular, the ten-year period for withdrawal and the ten-year bar are different periods. The current consolidated StAG, §§ 35 and 35a, governs these consequences; Correcting inaccurate or incomplete information explains the practical questions.
Families and particular life circumstances need their own assessment
Anyone married to a German citizen or in a registered civil partnership with one may fall within § 9 StAG. As a rule, this provides for three years of lawful habitual residence and a marriage or civil partnership that has existed for two years. The other statutory requirements still have to be assessed. This rule exists independently of the abolished reduction for special integration achievements.
For joint naturalisation, spouses or civil partners and minor children may also be naturalised together under § 10(2) after a shorter period of residence. This is a discretionary provision, rather than automatic acquisition through the naturalisation of a family member. The applicable requirements must be assessed for each person. Further circumstances are explained in Naturalisation in particular life situations.
Naturalisation is also possible before adulthood. From their 16th birthday, young people can generally take procedural steps themselves under § 34 StAG. Legal representatives act for younger children. Where parents are separated, it is therefore also necessary to establish who has parental responsibility and may submit the application. The question of representation must be distinguished from the child's substantive requirements. The 16th birthday affects procedural steps and language requirements in particular; the statutory possibility of inclusion in a joint naturalisation as a minor child ends only at 18. The article on age limits for children explains the consequences during a pending procedure.
Where a requirement for naturalisation by entitlement is missing, discretionary naturalisation under § 8 StAG is not automatically ruled out. However, it is not a general substitute for missing requirements either. Its statutory requirements and possible exceptions must be assessed separately.
What we clarify before and during your application
When preparing your application, we match each requirement to specific evidence. This makes clear whether a document is simply missing or a legal question remains unresolved. Missing proof of salary is different from a livelihood that is actually not covered; a variation in the spelling of a name requires a different explanation from a completely unknown identity.
We keep our assessment up to date throughout your procedure. We review changes to your employment, marital status or right of residence with you and report developments relevant to your application to the authority. Submitting an application freezes neither personal circumstances nor, as a rule, the legal position. We examine specific transitional provisions such as § 40a where relevant. Preparing the application and managing the procedure explains the necessary documents and procedural steps.
Under German law, existing citizenship generally no longer has to be relinquished. Whether it is actually retained also depends on the law of the country of origin; see Multiple citizenship and its consequences. Finally, naturalisation takes effect when the naturalisation certificate is handed over under § 16 StAG.
