1. Particularly practically relevant constellations regarding the naturalization requirements
From a lawyer's perspective, these are the most practically relevant cases regarding the requirements for naturalization:
The residency status changes during the procedure
The income situation changes during the proceedings.
There are no appointments available for the naturalization test.
Applicants have the wrong residence permit
The residence permit expired during a stay abroad.
Clients do not know which periods count towards naturalization and which do not.
The authority's jurisdiction changes due to a relocation .
dual or multiple nationality
Accusation of lack of loyalty to the constitution due to expressions of sympathy for terrorist groups (e.g. Hamas)
No valid passport available or passport not recognized
A criminal record prevents naturalization.
Periods of study are not recognized by the authorities as relevant time for naturalization.
2. Requirements for naturalization: What are the greatest risks?
The requirements for naturalization often seem manageable at first glance, but in practice, many applications fail due to avoidable problems . Applicants frequently don't know exactly which requirements they actually need to meet or what documentation is required. This leads to incomplete or unsuitable documents being submitted, which can result in inquiries or even the rejection of the application. Furthermore, the process remains a black box for many of those affected, and the procedure is hardly comprehensible.
Another major risk is the lengthy processing times . Procedures can be stalled for months or even years without any discernible progress, while case workers often fail to respond to inquiries or respond only very slowly. Furthermore, the longer the process drags on, the greater the risk that personal circumstances will deteriorate – for example, due to job loss or other changes in life situations – which can jeopardize the naturalization process.
3. When should I hire a lawyer for naturalization?
Seeking legal counsel can be beneficial even before submitting an application. This is especially true if it's unclear whether all the requirements for naturalization are met or if there are uncertainties regarding the necessary documents. Those who wish to complete the process as quickly and legally as possible can also benefit from early legal representation.
A lawyer is also advisable if the naturalization application has already been rejected or the process has stalled . If the authorities do not respond for an extended period or it is unclear how the process will proceed, legal support can help clarify the situation, assert your rights, and get the process moving again.

6. FAQ Naturalization Requirements
What are the basic requirements for naturalization in Germany?
These include legal residence (e.g. with a settlement permit or EU Blue Card), sufficient German language skills at B1 level, passing the naturalization test, securing one's livelihood without social assistance, and a commitment to the free and democratic basic order.
Do I have to give up my current citizenship?
Since the reform of January 19, 2024, dual citizenship is generally permitted. This means that in most cases you can retain your existing citizenship.
When must the requirements for naturalization be met?
The requirements must be met at the time of the official decision. This means that you can submit additional documents after submitting your application. However, changes during the process (e.g., unemployment) can also lead to the requirements no longer being met.
What can I do if I don't meet all the requirements?
In such cases, legal advice is recommended. An experienced lawyer can examine whether missing documents can be replaced by alternative evidence or whether other legal avenues can be pursued.

Court rulings on naturalization requirements
For the purposes of securing one's livelihood within the meaning of the German Nationality Act (StAG), employment history is decisive (Federal Administrative Court, judgment of February 19, 2009 – 5 C 22/08, para. 27; Higher Administrative Court of Saarland, decision of October 13, 2021 – 2 D 168/21; Administrative Court of Potsdam, judgment of May 28, 2021 – 9 K 2439/18; Administrative Court of Stuttgart, judgment of November 24, 2011 – 11 K 1058/11).
A mandatory requirement for naturalization under Section 10 of the German Nationality Act (StAG) is that the identity of the applicant for naturalization is clarified (Federal Administrative Court, judgment of 23 September 2020 – 1 C 36/19).
In cases of passportlessness, identity verification is carried out in a graduated procedure (Federal Administrative Court, judgment of 23.09.2020, 1 C 36/19).
An applicant for naturalization who, as a result of a fundamentalist cultural and value system, refuses to shake hands with any woman simply because she is of a different gender and is therefore considered per se to be a threat of sexual temptation or immoral behavior to the man, does not guarantee his integration into German society (VGH Mannheim, judgment of 20.8.2020 – 12 S 629/19).
Language certificates do not expire. While it is true that a so-called "loss of language skills" can occur if language knowledge is not used regularly, which can diminish the validity of a certificate, case law requires that "significant doubts" about the language skills must exist in the specific individual case (Higher Administrative Court of North Rhine-Westphalia, decisions of October 8, 2013 – 19 E 919/13 – juris para. 5 and of May 13, 2014 – 19 E 458/14 – juris para. 3 ff).
The glorification of Hamas on social media can lead to the revocation of naturalization due to deception regarding loyalty to the constitution (VG Berlin, decision of 20.05.2026, file no. 39 L 150/26).
Left-wing extremism can also block naturalization due to a lack of loyalty to the constitution (VG Stuttgart, judgment of February 6, 2026, case no. 4 K 797/24).
Only questions relevant to naturalization may be asked during the naturalization interview. No unnecessary questions may be asked at the naturalization appointment (see here).
