The path to naturalisation: from residence permit to German passport

The path to German citizenship can be divided into four stages. Each has its own legal framework in the Residence Act (Aufenthaltsgesetz, AufenthG) or the Nationality Act (StAG):

Important: not everyone goes through all four stages in this order. The settlement permit is not mandatory for naturalisation — a continuous residence permit can already be enough for the five-year period. Which permits count towards the naturalisation clock is explored in the comparison Residence vs. settlement permit. This article describes the stages generically; which station applies in your case is assessed by the competent authority — it does not replace individual advice.

At the start there is the residence permit (Aufenthaltserlaubnis) — a temporary residence title under the Residence Act. It is issued for a specific purpose: study, training, employment, family reunification or humanitarian grounds. The legal bases for issuance and purpose-binding are found in § 7 and the following provisions of the AufenthG. How this first application works — the application requirement (§ 81), the general requirements (§ 5), the visa procedure and the competent foreigners authority (§ 71) — is explained in Applying for a residence title: the first application; which types of title the Residence Act provides for in the first place is set out in Types of residence title.

For this first step: the permit is tied to a purpose and a deadline. Both become relevant in the later stages — the purpose must continue to apply when you renew, and the deadline marks the point by which the next application must be filed. How requirements differ by permit type (study, skilled worker, family, humanitarian) is described in Renewal by permit type.

The clock for naturalisation already starts in this phase: every day of lawful residence later counts towards the five years under § 10 StAG.

The residence permit expires — and must be renewed in good time, as long as the purpose of residence continues. Legally, a simple principle applies. § 8 (1) AufenthG states:

"The same provisions apply to the renewal of a residence permit as to its issuance." (own translation of "Auf die Verlängerung der Aufenthaltserlaubnis finden dieselben Vorschriften Anwendung wie auf die Erteilung.")

So for a renewal, essentially the same requirements must still be met as at first issuance — the purpose continues, livelihood is secured, a valid passport is available. The full guide: Renewing your residence permit.

The most important rule of this stage is in § 81 (4) sentence 1 AufenthG:

"If a foreigner applies before the expiry of his residence permit for its renewal or for a different residence permit, the previous residence permit is deemed to continue from the time of its expiry until the decision." (own translation)

This continuation fiction (Fortbestandsfiktion) means: anyone who applies before expiry remains lawfully resident until the authority decides — the chain stays gap-free. As proof you receive a fiction certificate (Fiktionsbescheinigung, § 81 (5) AufenthG). All details on deadlines and the certificate are in Deadlines & Fiktionsbescheinigung.

If, however, the application is filed only after expiry, this effect does not arise automatically; the authority may then order continuation only "to avoid undue hardship" (§ 81 (4) sentence 3 AufenthG) — a matter of discretion, not an entitlement. What applies in that case is covered in Residence permit expired.

Because the "staying" stage can repeat over years, it is the most common in practice — and the one where a gap costs the most. That is why the renewal is currently the point at which civitas. helps you complete and assemble your application.

After several years of continuously lawful residence, the next stage can follow: the settlement permit (Niederlassungserlaubnis). § 9 (1) AufenthG describes it as follows:

"The settlement permit is an unlimited residence title." (own translation of "Die Niederlassungserlaubnis ist ein unbefristeter Aufenthaltstitel.")

Unlike the residence permit, it is therefore no longer temporary and does not have to be renewed regularly. § 9 (2) AufenthG ties it to several conditions — among them five years of residence permit, secured livelihood, 60 months of pension contributions, sufficient German-language skills (level B1 under § 2 (11) AufenthG) and sufficient living space. For skilled workers there are faster routes: under § 18c (1) AufenthG usually after 36 months (shortened to 24 months with training/studies completed in Germany), and with an EU Blue Card under § 18c (2) AufenthG after just 27 or 21 months.

The full catalogue of requirements and the distinction from naturalisation is explained in Settlement permit: requirements under § 9 AufenthG.

Important for the journey: the settlement permit is a stage towards the goal, not the goal itself. It grants an unlimited right of residence — but the passport remains a foreign one. For many it is a sensible intermediate station; for naturalisation, however, it is not a mandatory requirement (see the next stage).

At the end of the path stands naturalisation under § 10 StAG — acquiring German citizenship. Under § 10 (1) StAG it requires in particular five years of lawful habitual residence and a qualifying residence title. Under § 10 (1) no. 2 StAG, sufficient for this is

"an unlimited right of residence or, as a national of Switzerland … a residence permit on the basis of the agreement of 21 June 1999 …" (own translation of "ein unbefristetes Aufenthaltsrecht oder als Staatsangehöriger der Schweiz … eine Aufenthaltserlaubnis auf Grund des Abkommens vom 21. Juni 1999 …")

— or a residence permit that can lead to permanent residence. This is exactly where the previous stages interlock: the settlement permit from stage 3 is such an unlimited right of residence; but the continuous residence permit from stages 1 and 2 can also satisfy the requirement.

The further naturalisation requirements — language skills, livelihood, commitment to the free democratic basic order, the naturalisation test and more — are a topic of their own and are covered in detail in the naturalisation articles. This hub only builds the bridge to them and deliberately does not go into the depth of § 10:

• Naturalisation requirements — what counts at the goal in detail.
• Naturalisation document checklist — which proofs the naturalisation application requires.

The thread running through all four stages is lawful residence. For § 10 StAG, five years count — and they must be uninterruptedly lawful. Every clean renewal (stage 2) keeps this chain closed; every gap can jeopardise it.

In concrete terms:

• Renewing on time keeps residence continuously lawful by virtue of the continuation fiction (§ 81 (4) sentence 1 AufenthG) — even while the authority is still deciding.
• A gap (a late application without an ordered continuation) can interrupt the lawfulness. Whether and how this affects the deadlines for a settlement permit or naturalisation is a case-by-case matter assessed by the competent authority — it cannot be stated in a blanket way.

Anyone who thinks of the path as a whole treats each renewal not as a chore but as a building block for the goal. At civitas. we currently support exactly this one stage — the renewal — with completing and compiling the application; the other stages are covered here for information only.

civitas. is a private application-assistance service — not a public authority and not a law firm. We provide no legal advice and no forecast of success, and we do not recommend to anyone which stage is "right for them" — that is assessed by the competent authority. What we do: we guide you through the details in a structured way, help you complete the applications and assemble the relevant document checklist so you can submit completely and on time.

The stage currently supported is the renewal — the point where most people are on their path.

What are the stages on the path to naturalisation?

Usually four: (1) first residence permit (§ 7, § 8 AufenthG), (2) renewal of the permit (§ 8, § 81 AufenthG), (3) — optionally — settlement permit (§ 9 AufenthG) and (4) naturalisation (§ 10 StAG). Not everyone goes through every stage; the order depends on the individual case, which the authority assesses.

Do I necessarily need a settlement permit for naturalisation?

Not necessarily. § 10 (1) StAG requires five years of lawful habitual residence and a qualifying title; that can be an unlimited right of residence (settlement permit), but also a residence permit that can lead to permanent residence. Details: Residence vs. settlement permit.

Which residence titles count for naturalisation — and which do not?

§ 10 (1) no. 2 StAG ties this to the type of title. Under it, sufficient is an unlimited right of residence (such as the settlement permit), an EU Blue Card or — in the wording of the statute — "a residence title for purposes other than those listed in §§ 16a, 16b, 16d, 16e, 16f, 17, 18f, 19, 19b, 19e, 20, 20a, 22, 23a, 24, 25 (3) to (5) and § 104c of the Residence Act" (own translation). In plain terms: a residence permit that can lead to permanent residence supports the requirement; purely purpose-bound titles limited to a specific purpose named in those provisions (for example certain study or temporary humanitarian stays) typically do not count for this. Whether a specific title qualifies in an individual case is assessed solely by the competent naturalisation authority; the § 10 details are covered in Naturalisation requirements.

Why is renewing on time so important for naturalisation?

Because § 10 StAG counts five years of uninterruptedly lawful residence. A renewal application filed before expiry keeps residence continuously lawful by operation of law under § 81 (4) sentence 1 AufenthG. More in Deadlines & Fiktionsbescheinigung.

What happens if a gap arises between two permits?

With a late application, no automatic continuation fiction arises; the authority may order continuation only in cases of undue hardship (§ 81 (4) sentence 3 AufenthG). Whether a gap affects later deadlines is a case-by-case matter for the authority — see Residence permit expired.

Do stays abroad count towards the five years — how long may I be away?

This is about physical residence abroad — not the legal gap caused by a late renewal application (see the previous question). For naturalisation, § 10 (1) StAG requires habitual residence in Germany; when a stay abroad interrupts it is governed by § 12b StAG. Under it: "Habitual residence in Germany is not interrupted by stays abroad of up to six months" (own translation of "Der gewöhnliche Aufenthalt im Inland wird durch Aufenthalte bis zu sechs Monaten im Ausland nicht unterbrochen."). Longer stays abroad are harmless only under the conditions set out there — for example if the return takes place within a period set by the foreigners authority. Whether a specific stay abroad interrupts the five years is assessed in each case solely by the competent naturalisation authority; the § 10 details are covered in Naturalisation requirements.

How long does the path to naturalisation take?

As an anchor, § 10 (1) StAG names five years of lawful habitual residence. A former special rule that shortened residence to three years for special integration achievements (§ 10 (3) StAG, old version) was repealed with effect from 30 October 2025; since then the uniform five-year period applies. The actual time until the application depends on the individual course (permit type, changes, creditable periods) and cannot be stated in a blanket way; whether and which periods count in an individual case is assessed by the competent naturalisation authority. The requirements in detail are covered in Naturalisation requirements.

Do asylum-procedure or Duldung periods count towards the five years?

This is purely a matter of classification that the authority assesses on a case-by-case basis. Legally: the residence permission (Aufenthaltsgestattung) during a pending asylum procedure (§ 55 (1) AsylG) and the toleration (Duldung, § 60a AufenthG) are not residence titles. The permission only allows residence for the duration of the asylum procedure; the toleration merely suspends deportation temporarily — "the obligation to leave the country of a foreigner whose deportation is suspended remains unaffected" (§ 60a (3) AufenthG, own translation). They therefore do not establish title-based residence. Whether and which prior periods count in an individual case towards the five years of lawful habitual residence under § 10 (1) StAG is assessed solely by the competent naturalisation authority; civitas. gives no individual assurance on this. Details: Naturalisation requirements.

Can I pursue the settlement permit and naturalisation in parallel?

Legally these are two separate procedures with their own requirements. Which order is sensible or possible in your case is assessed by the respective competent authority; civitas. gives no individual recommendation on this.

Does civitas. support all stages?

Currently we support the renewal in completing and assembling the application. The informational articles cover the whole path; the final assessment of each stage rests with the competent authority.
