ΕλληνικάThere is no general residence permit in German law. The Residence Act works through titles tied to a stated purpose, so the purpose of the stay decides which title can lawfully be issued and what it allows the holder to do. That makes the choice of route the most consequential decision in the case, because it also fixes when permanent residence comes within reach. On one route the answer is twenty-one months. On another it is five years.

Which residence titles exist?
The Act separates temporary from permanent titles. The Aufenthaltserlaubnis is granted for a defined purpose and a defined period, and is extended only for as long as that purpose survives. Above it sit the EU Blue Card and the ICT Card for intra-corporate transferees. At the top is the settlement permit, unlimited in time and carrying no restriction on employment, alongside the EU long-term residence permit under Section 9a AufenthG.
The visa route has to be settled before anyone travels. Nationals of most third countries need a national long-stay visa from the competent German mission, which is converted into a residence permit at the Ausländerbehörde after arrival. Nationals of privileged states, among them Australia, Canada, Israel, Japan, New Zealand, South Korea, the United Kingdom and the United States, may enter without a visa and apply once they are in Germany. The distinction is easily missed. Clients who arrive on a short-stay Schengen visa often assume it can be converted later. It cannot, and the only cure is to leave and begin the visa procedure properly.
Skilled workers: Sections 18a and 18b AufenthG
Sections 18a and 18b address recognized vocational qualifications and recognized academic degrees respectively. Both depend on recognition. A foreign qualification must be assessed as equivalent to its German counterpart, and in the regulated professions, including medicine, nursing and much of the technical trades, that assessment has to be complete before the permit can issue rather than run alongside it.
An applicant who starts recognition only after the employment contract is signed loses months. In our practice this is the commonest cause of delay in cases that present no substantive difficulty at all. Employers who need a post filled by a fixed date should therefore begin the procedure in parallel with recruitment rather than after it. A first indication of whether a qualification will be treated as equivalent can be obtained from the federal portal Anerkennung in Deutschland.
The EU Blue Card: Section 18g AufenthG
The Blue Card requires a recognized university degree and a binding contract paying at least a statutory minimum. Since 1 January 2026 that minimum has been €50,700 gross a year for standard occupations. For shortage occupations, for graduates within three years of completing their degree and for qualifying IT specialists, €45,934.20 gross a year is sufficient. The figures are reset annually, so a contract negotiated in December can fall below the threshold in January.
The IT route deserves particular attention because advisers regularly overlook it. German law allows an IT specialist with no university degree at all to obtain a Blue Card on the strength of three years of relevant professional experience at academic level acquired within the previous seven. For experienced developers and architects without a formal degree this is often the only workable route.
The Opportunity Card: Sections 20a and 20b AufenthG
Where no job offer is yet in place, the Opportunity Card allows a qualified foreign national to come to Germany for up to twelve months to look for skilled work. An applicant whose qualification is already fully recognized qualifies directly. Everyone else must score at least six points on a statutory scale crediting qualifications, recent professional experience, language ability, age and earlier lawful periods of residence in Germany. The language threshold is German at A1 or English at B2.
Means of support must also be shown, in 2026 roughly €1,091 a month and so €13,092 for a full card, evidenced by a blocked account, a formal declaration of commitment or a part-time contract reaching that figure. During the search the holder may work up to twenty hours a week and take trial employment of two weeks with any given employer. The card is designed to be exchanged for a skilled worker permit or a Blue Card once a suitable position is found. It does not carry family reunification, so the change of title should be planned before a spouse or children file applications of their own.
Study and the move into work: Sections 16b and 20 AufenthG
The academic route begins with Section 16b, which requires admission to a state or state-recognized institution, health insurance and proof of maintenance. In 2026 that means €11,904 held in a blocked account releasing €992 a month. Students may work 140 full days a year alongside their studies.
What happens after graduation is where the Act is at its most generous and least tolerant of poor timing. A graduate of a German institution has a statutory entitlement under Section 20 to as much as eighteen months in which to find work matching the degree, and may take any employment during that period. The entitlement exists only where the new title follows directly on from the study permit, and the application must reach the Ausländerbehörde before the existing permit expires. What matters most is that the eighteen months run from the date of graduation and not from the day the new card is issued. A graduate who waits for the formal certificate before acting loses part of the period without noticing.
Self-employment: Section 21 AufenthG
Section 21 covers several distinct situations rather than one. An applicant intending to establish or acquire a commercial business must show an economic interest or a regional need for the activity, a reasonable expectation of positive economic effect, and secured financing. The immigration authority assesses this with input from the competent chambers, working from a business plan and evidence of the applicant’s own qualifications. A takeaway food outlet is plainly weighed differently from an IT consultancy that will employ staff.
Members of the liberal professions face a lighter test. The distinction German law draws between a trade and a liberal profession should therefore be settled before a word of the application is drafted, since it governs both the depth of the examination and the documents to be filed. Turkish nationals occupy a special position under the standstill clause in the Additional Protocol to the EEC-Turkey Association Agreement, which has to be raised expressly because the authority will not apply it of its own motion.
Family reunification: Sections 27 to 36 AufenthG
Where the sponsor is a German national, Section 28 applies and the maintenance of the incoming spouse generally need not be proved. Where the sponsor is a third-country national living in Germany, Section 30 applies and the usual conditions of secure livelihood and sufficient living space are enforced. Both spouses must have reached eighteen, and the incoming spouse must ordinarily be able to communicate in simple German at A1 before the visa issues.
The exceptions to the language condition are broader than most applicants expect. It falls away where the sponsor holds an EU Blue Card or a skilled worker permit, where the sponsor holds a permit as a self-employed person or researcher, where another Member State has issued the sponsor an EU long-term residence permit, and where the sponsor is a national of one of the privileged states named above. For skilled workers the living space requirement also falls away for the core family. Children of sixteen and seventeen who do not move together with both parents are treated considerably more strictly under Section 32, and such cases should be structured early, because the position shifts again on the eighteenth birthday.
Settlement permit and naturalization
The routes to permanent residence differ greatly in length. Section 9 sets the general rule at five years of lawful residence, sixty months of pension contributions, German at B1, knowledge of the legal and social order, secure livelihood, adequate living space and health insurance. For skilled workers Section 18c shortens this to three years holding a title under Sections 18a, 18b or 18d, and to two years where the vocational training or the degree was completed in Germany. Blue Card holders reach the settlement permit after twenty-seven months of qualifying employment with elementary German, and after twenty-one months where B1 is demonstrated.
Naturalization is governed not by the Residence Act but by Section 10 of the Nationality Act, and now requires five years as a rule. The three-year route for exceptional integration introduced in 2024 was repealed with effect from 30 October 2025 without transitional provisions. Advice published in 2024 and 2025 that still rests on that route is out of date, and applications filed before the repeal but not yet decided are judged under the new law.
Registration, tax and duties to notify
Registering an address under Section 17 BMG does not only unlock the appointment at the immigration authority; it also establishes unlimited liability to German income tax. A person who under Sections 8 and 9 AO has a domicile or habitual abode in Germany is taxed there under Section 1 EStG on worldwide income, subject to the applicable double taxation treaty. Relocation planning that treats immigration separately from tax residence is incomplete, and that is particularly true of entrepreneurs and of employees who retain income sources in their home country.
A title also remains tied to its purpose after grant. If the employment on which a work-based permit rests comes to an end, the immigration authority must be told, and it will usually allow a limited period in which to find comparable work. Even the settlement permit lapses under Section 51 AufenthG if the holder leaves Germany for a reason that is not temporary in nature, or stays abroad for more than six months without having that period extended in advance. Anyone who will be absent for a prolonged period for family, business or medical reasons is better advised to clear it with the authority before departure than to explain it afterwards.
Conclusion
The difficulties we see in German immigration files rarely arise from the substantive law. They arise because the wrong statutory basis was chosen at the outset, because recognition of the qualification was left too late, or because one title was allowed to expire before the next was applied for. Where the facts are complicated, whether because a qualification is of uncertain equivalence, because a venture requires input from the chambers, or because a family holds several nationalities and several different titles, the analysis belongs before the application. A refusal on the file is a good deal harder to undo than a delay accepted at the planning stage.

Frequently asked questions
Can I enter on a Schengen visa and apply for the residence permit once I am in Germany? Only if you are a national of one of the privileged states. Otherwise a national long-stay visa must be obtained from the competent German mission before travel. A short-stay Schengen visa cannot be converted into a residence permit.
Do I need German for the EU Blue Card? Not in order to obtain it. German does affect when permanent residence becomes available: with B1 the settlement permit comes after twenty-one months instead of twenty-seven.
What happens if I lose my job? The loss must be notified to the immigration authority, which will usually allow a limited period in which to take up comparable employment. Inaction puts the title at risk; timely notification generally does not.
Can my family join me on the Opportunity Card? No. The Opportunity Card does not carry family reunification. The sensible course is to convert to a skilled worker permit or a Blue Card first and to apply for the family afterwards.
Is naturalisation after three years still available? No. That route was repealed with effect from 30 October 2025 without transitional provisions. The ordinary five-year period applies again.
