Hamas support: When can naturalization be revoked retroactively?

For many highly qualified professionals , expats, and international students, obtaining German citizenship is considered the final milestone of successful integration. It promises lasting legal security, unrestricted freedom of travel, and definitive equality in both private and professional life. Human resources departments (HR teams) also value this step for their international talent, as it secures long-term employee retention within the framework of global mobility. However, receiving a German passport is subject to strict legal conditions that remain relevant even after the official presentation of the naturalization certificate. A recent ruling by the Berlin Administrative Court clearly demonstrates that the seemingly secure status of citizenship can be revoked under certain circumstances if fundamental declarations of loyalty are violated.

Why was the naturalization revoked in this case?

The Berlin Administrative Court's decision concerns the case of a 35-year-old Palestinian man who received German citizenship in the fall of 2025 after a successful naturalization process ( Berlin Administrative Court, decision of May 20, 2026, case no. 39 L 150/26 ). Just one day after his naturalization , he posted a picture on Instagram showing alleged Hamas fighters , captioned "Heroes of Palestine" and accompanied by a green heart. A picture of the Hamas founder had already been shared via the account. The Berlin State Office for Immigration ( LEA ) reacted promptly and revoked the naturalization certificate only two months later. The Berlin Administrative Court has now ruled this revocation manifestly lawful in expedited proceedings . The judges made it unequivocally clear that expressing sympathy for a terrorist organization is incompatible with the fundamental values of the German state.

What legal framework governs the revocation of a passport ?

In our daily practice advising on visa and immigration law, we observe that many people underestimate the implications of the loyalty declarations they have signed. The legal basis for revocation is Section 35 of the Nationality Act (StAG) . According to this section , naturalization can be revoked if it was obtained through fraudulent misrepresentation , threats, or bribery. Anyone who affirms their support for the free democratic order during the naturalization process but secretly supports extremist or terrorist organizations is fraudulently deceiving the authorities. Although such revocations were historically rare, with a maximum of 60 cases per year, the authorities are recording a clear upward trend: In 2025, 561 naturalizations were revoked. This demonstrates that security and immigration authorities are now monitoring compliance with the requirements far more rigorously than just a few years ago.

What has changed with the new nationality law in 2024?

With the comprehensive reform of the Nationality Act in 2024, the legislature tightened the hurdles for obtaining and maintaining German citizenship . At the heart of this reform is the legal anchoring of Germany's historical responsibility. According to Section 10, Paragraph 1, Sentence 1, No. 1a of the Nationality Act, applicants must now explicitly acknowledge responsibility for the Nazi regime of injustice and its consequences, particularly the protection of Jewish life . Furthermore, the law requires a commitment to the peaceful coexistence of nations. Section 10, Paragraph 1, Sentence 3 of the Nationality Act further clarifies that antisemitic, racist, or other acts motivated by contempt for humanity are incompatible with the guarantee of human dignity enshrined in the Basic Law (German Constitution). Anyone who signs this declaration but simultaneously endorses the ideology of Hamas forfeits their right to a passport , as the court considers the organization's objectives to be incompatible with nationalism. Such misconduct categorically precludes naturalization under Section 11, Sentence 1, No. 1a of the Nationality Act.

What consequences are there for corporate immigration and family reunification ?

For foreign young professionals, academics, and their employers, such legal proceedings have serious consequences that extend far beyond the loss of a passport . If naturalization is retroactively revoked under Section 35 of the German Nationality Act (StAG), the legal status as a German citizen is completely lost . This means that the person in question is legally considered a foreigner again and, by law, requires a valid residence permit under the Residence Act (AufenthG). Whether and in what form a new visa will be granted is extremely questionable after proven fraudulent misrepresentation and suspicion of supporting terrorism; deportation is often a threat. Such a scenario not only destroys a professional career in Germany but also has a massive impact on the stability of family relationships . Subsequent family reunification for spouses or children loses its legal basis, as the privileged right to join a German citizen no longer applies. Companies and HR departments that recruit international talent as part of global mobility should therefore proactively ensure that their foreign employees are fully aware of the strict legal framework and the importance of social media activities in the naturalization process.

Conclusion

The Berlin Administrative Court's decision underscores that the new citizenship law is not a mere formality, but rather demands a substantive commitment. A single careless post on social media can be enough to derail the entire naturalization process and the associated life plans. For qualified professionals , expats, and employers, the following applies: German citizenship offers outstanding privileges, but requires a complete and honest identification with the fundamental values of the law. As a law firm specializing in visa law and corporate immigration, we recommend a thorough and early review of all legal requirements to eliminate risks to residency and family reunification from the outset.
