EU Blue Card: Settlement Permit and Naturalization

The EU Blue Card, governed by Section 18g of the Residence Act (Aufenthaltsgesetz, AufenthG), is a temporary residence permit for highly qualified employees who hold a recognized academic degree, an equivalent tertiary qualification, or — in the field of information and communications technology (ICT) — relevant professional experience. It is a time-limited residence title, generally valid for four years.

To enter Germany, third-country nationals generally require a visa or another qualifying residence permit. Once in possession of this, highly qualified skilled workers can apply for the EU Blue Card at their local foreigners’ authority (Ausländerbehörde) — the competent authority being determined by the applicant’s place of residence, or intended place of residence.

Several requirements must be met to apply for the EU Blue Card, beginning with the professional qualification noted above. In addition, a work contract or a concrete job offer meeting the conditions of Section 18(2)(1) AufenthG must be in place, providing for employment of at least six months (Section 18g(3) AufenthG). The applicant must also demonstrate a minimum gross annual salary of €50,700 (as of 2026). For shortage occupations — such as doctors, senior IT managers, and STEM professionals — as well as for career entrants, a lower annual salary of €45,934.20 (as of 2026) is sufficient, provided the approval of the Federal Employment Agency (Bundesagentur für Arbeit) has been obtained.

The recognition and equivalency assessment of qualifications obtained abroad is a frequent source of early difficulties. At Schlun & Elseven, our immigration lawyers are on hand to advise you throughout the application process. We assist with compiling all required documents, handle communication with the competent authority, and answer any questions that arise. Our immigration lawyers also represent you in cases of refusal or withdrawal of the EU Blue Card.

German residence law draws a distinction between temporary residence and permanent settlement. The time-limited residence permit granted through the EU Blue Card already allows holders to take their first steps toward a permanent residence title during its period of validity.

The settlement permit (Niederlassungserlaubnis), governed by Section 9 of the AufenthG, is an indefinite residence title that secures the holder’s right to remain in Germany permanentlys. Under Section 9(2)(1) AufenthG, the standard requirement is five years of continuous valid residence. For qualified skilled workers and EU Blue Card holders, however, the path is considerably eased. Under Section 18c(1) AufenthG, skilled workers meeting the relevant conditions can obtain the settlement permit without the approval of the Federal Employment Agency. One requirement is that the skilled worker must have held a residence title under Sections 18a, 18b, 18d, or 18g AufenthG for at least three years.

Under Section 18c(2)(1) AufenthG, EU Blue Card holders are entitled to the settlement permit — as a departure from the standard route — provided:

• they have been in qualifying employment under Section 18g AufenthG for at least 27 months,
• they have made compulsory or voluntary contributions to the statutory pension insurance (gesetzliche Rentenversicherung) — Germany’s public pension system — for that period, or can demonstrate equivalent contributions to a comparable insurance or pension scheme,
• the conditions of Section 9(2)(1)(2), (4)–(6), (8) and (9) AufenthG are met (including a secure livelihood, no grounds of public safety or order that would preclude the grant, and authorization to work), and
• they have basic knowledge of the German language.

Where the applicant has sufficient German language skills at B1 level on the Common European Framework of Reference (CEFR), the qualifying period can be reduced to 21 months under Section 18c(2)(2) AufenthG.

German citizenship can be acquired through naturalization (Einbürgerung). To qualify, the conditions set out in Section 10 of the Citizenship Act (Staatsangehörigkeitsgesetz, StAG) must be met:

• the applicant has lawfully resided in Germany on a habitual basis for five years,
• the applicant’s identity and nationality have been established,
• the applicant has declared their commitment to the free democratic basic order of the Federal Republic of Germany and to Germany’s special historical responsibility arising from the National Socialist regime and its consequences,
• the applicant holds an indefinite right of residence, the EU Blue Card, Swiss citizenship, or an equivalent status (see Section 10(1)(2) StAG),
• the applicant’s livelihood is secure without recourse to social welfare,
• the applicant has not been convicted of a criminal offense,
• the applicant has sufficient knowledge of the German language at B1 level, as well as knowledge of Germany’s legal and social order and living conditions.

Foreign skilled workers who hold an EU Blue Card or a settlement permit are therefore already in a position to satisfy at least the required residence status condition.

Schlun & Elseven is pleased to assist with compiling all required documents and submitting your naturalization application. Our immigration lawyers advise you throughout the entire procedure.

The settlement permit grants an indefinite right of residence — you no longer need to concern yourself with renewals. Holders are also free to travel abroad for shorter periods without any risk to their permanent residence status. If you intend to leave Germany for an extended period, however, this could result in the settlement permit lapsing. As a rule, the settlement permit becomes invalid six months after departure. In such cases, it is important to apply in advance for authorization to remain abroad for longer than six months. An exception applies where the permit holder has reached the age of 60 and has resided lawfully in Germany for at least 15 years; under certain conditions, the same applies to that person’s spouse. In these cases, the settlement permit may not lapse until 12 months after departure.

German citizenship, by contrast, confers unrestricted freedom of movement within Germany — you are free to choose where within the country you wish to live. Freedom of movement also applies across the EU, allowing German citizens to live and work in any EU member state.

The settlement permit opens up the full German labor market to its holder. This indefinite residence title also makes changing jobs considerably more straightforward: unlike the situation under the EU Blue Card, holders of a settlement permit are not required to notify the foreigners’ authority when changing employer.

German citizens have access to all professions and enjoy full freedom of occupational choice in Germany.

The settlement permit not only allows the holder to remain in Germany indefinitely — it also simplifies family reunification. Among the conditions that must be met are the general requirements of Section 5(1) AufenthG, and adequate housing must be available for the entire family, as required by Section 29(1)(1) AufenthG.

Naturalized citizens enjoy full voting rights, easier access to social benefits, and a similarly simplified route to family reunification. Our immigration lawyers are pleased to assist with bringing family members to Germany. We clarify any open questions, handle communication with the competent authority, and help you compile the required documentation.

Obtaining a residence title such as the EU Blue Card or the settlement permit can be a demanding process. The following aspects are particularly worth noting:

• Language requirements: The required B1 level is often the first hurdle. Many highly qualified professionals underestimate the time and effort involved and start intensive language training too late. We recommend beginning a B1 language course as soon as you receive your EU Blue Card.
• Continuity of employment: For EU Blue Card holders, a period of unemployment — even of just a few weeks — can be problematic. Ensure there are no gaps in your employment record when changing employer. If you change jobs within the first year, the competent authority must be notified, and will then assess whether the conditions for your residence status continue to be met.
• Income and financial resources: When assessing a settlement permit application, the competent authority examines whether the applicant’s income provides a secure and self-sufficient basis for the future. There are no fixed thresholds; this is assessed individually for each applicant. Our lawyers are happy to explain which factors the authority takes into account in this assessment.
• Criminal law and residence status: A criminal conviction can not only prevent the grant of a residence title from the outset but can also affect an already existing status. In some cases, a title already issued may be revoked or withdrawn, or the person may be subject to expulsion — see Section 51(1)(3)–(5) AufenthG.
