Not everyone has to submit a B1 language certificate and proof of passing a naturalisation test when applying for naturalisation. Age-appropriate requirements apply to children under 16. For certain former guest workers and contract workers, and spouses who joined them, oral communication in everyday life is sufficient. The decisive factors are age or the individual’s immigration history. A long period of residence alone does not replace these conditions.

Understanding three different reductions in requirements

The general rule requires German at B1 level and knowledge of the legal system, society and living conditions in Germany. The exceptions change different parts of these requirements: for younger children, language is assessed according to their development. For labour migrants covered by the statutory concession, the language requirement is limited to oral communication. Neither group has to take a naturalisation test if the respective applicable conditions are met. This follows from § 10 StAG.

Reduced language requirements do not replace the other conditions

A reduced language requirement does not mean automatic naturalisation. Identity, the right of residence and the other requirements still need to be assessed. Conversely, an authority may not demand B1 simply because it appears on its general checklist of documents. First, it must establish which statutory rule applies to the individual. The overview of reduced requirements and exemptions also explains health-related exceptions and language hardship cases.

Children under 16: language development is what counts

What age-appropriate language development means

For a child who is not yet 16 at naturalisation, age-appropriate language development is sufficient under § 10 paragraph 4 sentence 2 StAG. The authority may therefore not use the abilities of an adult B1 examination candidate as the general standard. A nursery-age child does not need to be able to read letters from authorities independently or complete a written language test. For a school-age child, however, language development and participation in lessons taught in German are relevant.

The issue is the development of German language skills. A child’s ability to communicate well in the family language does not fully answer this question. Equally, multilingualism is not a deficit in itself. What matters are observations of whether the child understands, responds and expresses themselves in German at their particular age. Rigid requirements that disregard the specific stage of development do not fit the statutory standard.

For school-age children, we examine school reports as the evidence specified in the Interior Ministry’s guidance. For our assessment, we need current school reports including supplementary comments. A simple school attendance certificate, by contrast, mainly confirms attendance. It may be helpful, but may say little about language development. For younger children, an account from their childcare setting can explain their abilities; we clarify with the competent authority which documents are needed.

Looking more closely at developmental delays

If school performance is weak, we examine what it means for language development; it does not automatically establish insufficient language skills. Difficulties in mathematics, frequent changes of school or only a short time in the German school system need to be assessed differently from a significant language development disorder. We explain factually the basis of an unfavourable assessment and the child’s progress.

If the child has an illness or disability, the separate exemption under § 10 paragraph 6 StAG may be relevant alongside the child-appropriate standard. This is particularly important if health reasons prevent the child from achieving even age-appropriate development. We explain the impairment using suitable medical or developmental records. The requirements are covered in the article on Illness, disability and age-related limitations.

Why the 16th birthday matters during the procedure

For the reduced language requirement, the law expressly refers to age at the time of naturalisation. An application at age 15 therefore does not preserve the child-appropriate standard indefinitely. If the child turns 16 before the procedure is completed, the regular language requirement must generally be assessed unless another exception applies.

This does not necessarily mean that an additional external language examination will be needed. A suitable German school-leaving qualification or an appropriate school history may already demonstrate the skills. We therefore clarify early which existing school evidence will be recognised. Further details are available under alternative language evidence through school, vocational training and university studies.

Under § 34 StAG, children under 16 do not have capacity to conduct the proceedings themselves. The civic knowledge requirement does not apply to them by virtue of § 10 paragraph 1 sentence 2 StAG. They therefore do not need a naturalisation test. From the 16th birthday, this issue must also be reassessed; suitable school evidence may still make a test unnecessary. The end of the reduced language requirement for children is not the end of minority, which continues until 18. A young person may therefore already be able to act independently in the naturalisation procedure while still generally belonging to the category of minors eligible for naturalisation together with a parent. The further conditions for this must be assessed separately. Under § 16 StAG, naturalisation is completed when the certificate is handed over. If that occurs after the birthday, an earlier positive notification is not enough to preserve the previous age standard. The question of a joint application is addressed in the guidance on naturalisation of children together with a parent or on their own application.

Which former workers are covered

Guest workers in the former Federal Republic

The special rule covers people who entered the former Federal Republic under an agreement on the recruitment and placement of workers on or before 30 June 1974. The law defines the territory as it stood on 2 October 1990. It refers to a particular form of labour migration, rather than every earlier move followed by employment.

Two questions must therefore be distinguished: when did the person enter, and on what basis? Employment dating back to the early 1970s may be an important indication. It does not, however, establish on its own that entry was based on a recruitment agreement. Nor is nationality of a country from which workers were recruited sufficient in itself.

The statutory concession recognises that many members of this generation were initially expected to stay only temporarily and received little language support. People within the defined group do not also have to prove that they personally made use of every learning opportunity available at the time.

Contract workers in the former GDR

For contract workers, a separate entry cut-off date of 13 June 1990 applies. They must have entered the territory of the former GDR as contract workers. A later employment contract in the new federal states does not establish this status retrospectively. Nor is an earlier stay in the GDR for another reason, such as solely for study, sufficient.

We compare current document terminology with the statutory criteria without requiring identical wording. What matters is the actual historical employment and entry situation. We explain differing terms in documents in their historical context rather than merely stating a current job title. The former status may remain relevant to naturalisation despite later changes of occupation, self-employment or retirement.

Spouses who joined workers and the limits of the family rule

The concession also applies to spouses who joined a covered person within a temporal connection to that person’s arrival. Their inclusion is expressly provided for by law and covers both language and the naturalisation test. Here too, the lack of earlier integration opportunities is taken into account.

We set out the recruited person’s entry date, the spouse’s arrival date, the family relationship and the connection between the two periods of residence. The BMI application guidance from 2025 generally uses a period of ten years as a guide for the temporal connection. This administrative interpretation must be distinguished from the two statutory entry cut-off dates. The expression “temporal connection” appears in the law; it does not contain a separate rigid ten-year limit. Nor must the spouses who joined workers themselves have entered before the guest worker or contract worker cut-off date. For them, the decisive factor is the temporal connection to the arrival of the covered person they joined.

The concession does not extend generally to all relatives. Adult children or grandchildren do not benefit solely from the labour migration of their parents or grandparents. Their own requirements and, where relevant, their own exceptions apply. A marriage entered into much later or a substantially later move to join a spouse also needs separate assessment; a present-day marriage certificate alone does not answer the question of historical family reunification.

How to document the immigration history

If documents are missing after decades, we review with you the remaining evidence of entry and employment history. This makes careful compilation particularly important. According to the BMI application guidance, relevant documents include, in particular, earlier employment contracts, residence papers, work permits, visas or identification cards (Legitimationskarten). Together, they can show how the person was recruited and when they took up employment.

Pension records and insurance contribution histories can provide additional indications of timing. Their evidential value should not be overstated: a contribution period does not automatically explain the legal basis of the original entry. Conversely, the absence of a contribution period does not conclusively prove that no qualifying employment existed. Especially for former GDR contract workers, information about another pension system having been responsible at the time may be important.

We therefore bring together the evidence establishing the eligible category:

Establish that the person belongs to the covered group

  • a brief timeline of entry, first employment and subsequent periods of residence;

  • surviving documents showing dates and the reason for residence or employment at the time;

  • for spouses, documents relating to the marriage and the actual move to join the worker;

  • an explanation of which older documents are missing and which authorities might still hold them.

The citizenship authority can take existing official information into account, for example from the Central Register of Foreigners or the immigration authority. A missing register entry does not automatically prove a different immigration history. A coherent account supported by circumstantial evidence is considerably more informative than simply stating that someone has “always been a guest worker”.

What oral communication requires

For covered guest workers, contract workers and spouses who joined them, communicating in German in ordinary everyday situations is sufficient. Written skills at B1 level are not required under this special rule. This concerns, for example, being able to speak understandably about one’s family, housing or everyday matters and to understand simple questions.

The BMI application guidance envisages, in particular, a personal conversation for this purpose. A considerate approach using slow, clear speech is possible. Flawless grammar, an accent-free pronunciation or specialist legal terminology is not the aim. The person concerned must, however, be able to communicate themselves. If a relative translates or provides every answer, this does not demonstrate the applicant’s own German skills.

Suitable existing language evidence can make the assessment easier. According to the application guidance, evidence at a level of at least A1 is sufficient for these oral requirements. This does not create an obligation to book a new A1 examination before applying. If you can demonstrate the required communication in conversation, we clarify this evidence option with the authority.

Under § 10 paragraph 6 sentence 2 StAG, this group does not have to take the naturalisation test. This exemption concerns the statutory civic knowledge requirement. It does not remove other requirements, in particular the declarations of commitment required in each case and the absence of statutory grounds for exclusion.

How we assess health, income and language separately

If illness, disability or age-related limitations prevent a covered older person from meeting even the oral communication requirement, § 10 paragraph 6 sentence 1 StAG may additionally apply. The guest worker rule does not exclude this more extensive exemption. It is then necessary to examine which specific impairment prevents communication; receipt of a pension alone is not sufficient.

A special rule on securing a livelihood also applies to the same historical group. It additionally requires that the person is not responsible for their reliance on benefits under SGB II or SGB XII. This additional condition belongs to the income assessment, not to the language concession. Meeting the language rule does not resolve the livelihood question.

Since 1 July 2026, the cash benefit under SGB II previously known as Bürgergeld has been called Grundsicherungsgeld. This is confirmed by the current § 19 SGB II and the BMAS announcement on its entry into force. For § 10 StAG, classification under the relevant book of the Social Code remains decisive. Basic income support in old age under SGB XII must be distinguished from this. The special income exception for guest workers and spouses who joined them explores this separate assessment in more detail.
