We examine the exact legal basis of your residence permit and clarify whether naturalisation requires a change of title. The duration shown on the card and permission to work do not answer this question on their own. Knowing the exact statutory provision helps you identify whether your current permit is generally sufficient or whether you first need a different residence status.

First, read the legal basis in full

The electronic residence permit or its supplementary sheet usually states the statutory basis. Not only the section number matters, but also the paragraph and, where applicable, the sentence. Particularly for humanitarian residence permits, two permits with the same section number may need to be assessed differently for naturalisation.

We compare the details on your document with the latest decision. Having originally entered Germany with a particular visa does not necessarily tell you anything about the current permit. Similarly, the description “work permit” is too imprecise: gainful employment may also be permitted during residence for study, protection or family reasons. The legal basis of the right of residence remains decisive.

This article addresses which permits qualify for naturalisation by entitlement under § 10 StAG. The overview of the required residence status explains the relationship with the duration of residence and the time of the decision. Those entitled to freedom of movement can find the special rules in the article on EU, EEA and Swiss nationals.

How the statutory list of exclusions works

In addition to permanent rights of residence and the EU Blue Card, § 10 paragraph 1 sentence 1 number 2 StAG generally permits residence permits that do not serve an expressly excluded purpose of residence. The law therefore distinguishes between legal categories. It does not require an additional individual assurance for every temporary permit that a settlement permit will definitely be issued later.

Limits of excluded residence permits

An excluded permit does not become suitable because of a long period of residence, a high income or a permanent employment contract. These circumstances may be relevant to other naturalisation requirements or to a change of permit. However, they do not replace the status requirement. Conversely, the mere fact that a suitable residence permit is temporary does not justify a blanket demand to obtain a permanent permit first. The current version of § 10 StAG is decisive.

Which permits are generally suitable

Permanent permits and the EU Blue Card

A valid settlement permit generally satisfies the status requirement discussed here. The same applies to a German EU long-term residence permit. The EU Blue Card is expressly listed as an alternative in the StAG. It is currently regulated in § 18g AufenthG; older documents sometimes still refer to an earlier section number.

Issuing an EU Blue Card requires its own conditions under residence law to be met, for example regarding qualifications and employment. The wish to become naturalised does not in itself create an entitlement to this card. Someone who already holds another suitable residence permit therefore does not need to switch to an EU Blue Card solely for naturalisation. The current legal basis is set out in § 18g AufenthG.

Employment, research and self-employment

Temporary permits that are generally suitable include, in particular, residence permits for skilled workers under §§ 18a and 18b AufenthG, for research under § 18d and for other employment purposes under § 19c. Neither § 19d for qualified people whose stay was previously tolerated nor § 21 for self-employment appears in the list of exclusions.

The exact provision is decisive. Research under § 18d must be assessed differently from the expressly excluded residence for mobile researchers under § 18f. Similarly, the ICT Card is not a generally suitable employment permit for naturalisation, even though its holder works in Germany. Professional activity alone cannot replace the statutory distinction.

Family reunification and certain humanitarian permits

Residence permits for family reasons, such as under § 28 for family reunification with German nationals or under § 30 for joining a spouse, are generally suitable. The same applies, where the respective conditions are met, to other family permits that are not excluded. The right of residence must actually exist; simply being married or being a parent does not replace a required grant of a permit.

In the humanitarian category, residence permits under § 25 paragraph 1 and paragraph 2 are particularly relevant as suitable permits. Paragraph 2 covers both recognised refugees and people entitled to subsidiary protection. Residence permits under §§ 25a and 25b and under § 23 also generally fall outside the exclusions. In each case, this means only that these permits do not fail the status requirement; all the other naturalisation requirements still need to be assessed in full.

Which permits are insufficient for an entitlement

The exclusions can be organised by subject matter. This grouping provides guidance; the individual provisions remain legally decisive.

Training, study and preparation

Excluded training and study permits

Residence permits for the following purposes are excluded:

  • § 16a AufenthG: vocational training and further vocational training;

  • § 16b AufenthG: study;

  • § 16d AufenthG: measures for the recognition of foreign professional qualifications;

  • § 16e AufenthG: EU study-related internship;

  • § 16f AufenthG: language courses and school attendance;

  • § 17 AufenthG: seeking a vocational training place or a place at university.

This list does not mean that everyone in education or training is excluded from naturalisation. Someone who is studying but holds a suitable residence permit for family reasons, for example, must be assessed differently from someone with a permit under § 16b. The permit is decisive, not just the person's everyday activity.

§ 16g also deserves separate consideration: this residence permit for vocational training for foreign nationals required to leave Germany does not appear in the current list of exclusions. It must therefore not be treated as automatically equivalent to § 16a solely because its purpose is training. Whether the required period of lawful residence has already been completed is a different question; earlier periods of tolerated stay do not retrospectively become lawful because of the new permit. The basis is § 16g AufenthG.

Mobility, voluntary service and job seeking

Further exclusions concern § 18f AufenthG, the ICT Card under § 19, the Mobile ICT Card under § 19b and European voluntary service under § 19e. They also include § 20 for job seeking following certain types of residence and § 20a for the Opportunity Card.

For the Opportunity Card in particular, the similarity in name to the Blue Card is misleading. The EU Blue Card is expressly suitable; the Opportunity Card is on the list of exclusions. If an offer arises during a job search, we assess whether and when the conditions of a suitable employment residence title are met. The job offer alone does not change the existing card.

Certain humanitarian purposes of residence

§ 22, § 23a, § 24 and § 25 paragraph 3 to 5 AufenthG, including the special paragraphs within that range, are also excluded. This means, for example, that temporary protection under § 24 and a residence permit based on a national prohibition of deportation under § 25 paragraph 3 are insufficient for an entitlement.

§ 25 paragraph 2 and § 25 paragraph 3 are not interchangeable. Both may relate to a need for protection, but they differ in their statutory basis and their treatment for naturalisation. Similarly, § 23a must not be confused with § 23. Using only the term “humanitarian residence permit” conceals precisely the distinctions that matter.

What now applies to the opportunity-based right of residence

§ 104c AufenthG is also included in the list of exclusions. Under the version in force on 17 October 2026, this provision contains a transitional rule for opportunity-based residence permits already issued. A permit that is still valid remains in force until the end of its validity; it has therefore not disappeared simply because of the legislative change. As such, it remains insufficient for naturalisation by entitlement.

The transitional rule also provides that an extension is possible only as a residence permit under § 25a or § 25b. Under § 104c paragraph 2, an application for a different permit does not have the effect provided for in § 81 paragraph 4. A general recommendation to apply for any new permit and rely on continuation of the existing permit would therefore be wrong here. The current transitional rule in § 104c AufenthG is decisive.

Older lists can lead to unnecessary changes of permit

The assessment must be based on the law in force. In particular, the 2024 reform removed § 18d and § 23 paragraph 1 from the list of exclusions. Information that continues to describe these provisions as generally unsuitable does not accurately reflect the current list. The Opportunity Card and changes to section numbers also require attention.

For a pending application, we examine both your title and the version of the law on which official information relies. Advice that was once correct may now be outdated. Conversely, an earlier, more favourable statement does not justify assuming that every later change in the law is irrelevant to your own application.

How we prepare a necessary change of residence title

Changing a permit is a separate procedure under residence law handled by the immigration authority. First, it must be established which new permit is a possibility in light of the person's actual circumstances. After completing a degree, for example, this may be a skilled worker permit. Where there is a suitable family situation, residence for family reasons may become relevant. The requirements, evidence and possible restrictions on changing permits differ.

We examine your existing title, the potential new legal bases and the evidence they require. For employment, we consider qualifications, recognition and the employment contract; for family rights, civil-status records and family circumstances. We do not select a title merely because its number is absent from the exclusion list: its own conditions must be met.

Where several residence options are available, we discuss their overall effects with you: ties to an employer, continued validity after family changes and longer-term residence security. We include your naturalisation goal without overlooking the independent requirements of residence law.

What an application to change permits does not yet achieve

Continuation of the existing permit

An application submitted in time may allow the existing permit to continue under the conditions of § 81 paragraph 4 AufenthG. Continuation means continuation of the old permit. Someone who holds an excluded study permit and applies for an EU Blue Card does not hold the EU Blue Card merely by having submitted that application.

This matters when coordinating the two procedures. The naturalisation authority can be informed of the application submitted and, later, provided with evidence of the grant. Until the suitable status exists, however, a positive forecast alone does not satisfy the status requirement. A Fiktionsbescheinigung must therefore be read together with the previous permit. The basis of the general continuation rule is § 81 AufenthG.

Does the residence period start again after the change?

A proper change between residence permits does not automatically reset the residence period to zero. The previous period is assessed under the rules on lawful habitual residence. Periods of study may therefore remain relevant even though § 16b is excluded as a current permit for an entitlement. Nor may a blanket rule counting only half the time, used in other residence-law procedures, be transferred to naturalisation without examination.

The situation differs where there are actual interruptions or periods that do not count because of their legal nature. A separate calculation and, where appropriate, consideration of § 12b StAG may be necessary here. The detailed article on study, training and permission to remain during asylum proceedings addresses these periods; return deadlines and gaps in residence explains interruptions.

Do not equate the requirements for the new permit with naturalisation requirements

Successfully changing to a residence permit under § 25a or § 25b is an important step under residence law. However, the earlier periods of residence taken into account for this may also include periods of tolerated stay or permission to remain during asylum proceedings. This does not mean that the same periods count in full for naturalisation. The statutory standards for language skills or financial security may also differ.

Once a suitable title is granted, we continue the naturalisation assessment under the requirements that actually apply. The new permit resolves the question of current status; it does not also certify that all the requirements of the StAG are met. This distinction prevents both an unnecessary restart of the residence period and a premature assumption that the change of permit has already created the full entitlement to naturalisation.

Proving the change of permit and identifying its place in both procedures

Following a change, we document in the naturalisation application which new title was actually granted and when it took effect. The decision granting it, or unequivocal confirmation from the immigration authority, and the new document provide this evidence. An acknowledgement of receipt of the application to change permits, an appointment confirmation and an employment contract each prove something different. If the card is still being produced, we clarify the legal act already completed and proof of the existing right.

We document the transition from the old to the new title so that the naturalisation authority can follow both periods. A Fiktionsbescheinigung relates to the earlier permit and the underlying application, whereas evidence of the grant relates to the new status. This enables the naturalisation authority to assess both the intervening period and the suitability of the status today. Merely stating “now employed” leaves open whether only employment has so far been permitted or whether a permit for a suitable purpose of residence has already been granted.

For people entitled to protection, a distinction must also be made between the BAMF decision and the immigration authority's grant of a residence permit. A recognised entitlement to protection may open the way to a residence permit, but does not generally replace proof of that permit. Further questions about the form of protection, documents and crediting periods are covered in naturalisation with refugee protection and other protection status. Once the suitable status is established, the duration of residence, identity, livelihood and required knowledge, in particular, must still be assessed independently.
