Dual Citizenship in Germany: Rules and Exceptions


Germany has long been known for its strict citizenship laws, often requiring individuals to renounce their previous nationality before becoming German citizens. However, in recent years, the country has made significant changes to its dual citizenship policies, allowing more people to retain their original nationality while acquiring German citizenship. Understanding the rules and exceptions surrounding dual citizenship in Germany is crucial for those considering naturalization or seeking to maintain their existing citizenship status.

General Rules for Dual Citizenship in Germany

The general principle in German nationality law is that individuals must hold only one citizenship. According to the German Nationality Act (Staatsangehörigkeitsgesetz), foreigners who wish to become German citizens through naturalization are typically required to renounce their previous nationality. This policy aims to ensure that new citizens are fully integrated into German society and demonstrate their allegiance to the country.

Despite this general rule, there are several important exceptions that allow certain individuals to hold dual citizenship. These exceptions apply to specific groups, including individuals born in Germany to foreign parents, EU citizens, refugees, and those granted special permission.

Dual Citizenship by Birth in Germany

Children born in Germany to foreign parents may acquire dual citizenship under certain conditions. If at least one parent has been legally residing in Germany for at least eight years and holds a permanent residence permit, their child automatically obtains German citizenship at birth. In such cases, the child retains their parents’ nationality in addition to German citizenship.

Previously, these children were required to choose one nationality by the age of 23 under the “option obligation” (Optionspflicht). However, reforms in 2014 removed this requirement, allowing eligible individuals to retain both citizenships permanently. This change has benefited many children of immigrants, particularly those from Turkey and other non-EU countries.

Dual Citizenship for EU Citizens

Germany has a more lenient approach toward dual citizenship for citizens of European Union (EU) and European Economic Area (EEA) member states. Individuals from these countries who acquire German citizenship through naturalization are not required to renounce their original nationality. This policy aims to promote European integration and facilitate mobility within the EU.

Similarly, German citizens who acquire the nationality of another EU or EEA country do not automatically lose their German citizenship. This provision allows for greater flexibility and ensures that individuals can benefit from the rights and privileges of both nationalities.

Dual Citizenship for Refugees and Asylum Seekers


Refugees and asylum seekers granted protection status in Germany may also be allowed to retain their original nationality when naturalizing as German citizens. Due to humanitarian considerations, Germany does not require refugees to renounce their previous citizenship if doing so would pose a significant legal or personal hardship. This policy applies particularly to individuals from countries where renouncing nationality is difficult or impossible due to restrictive government policies or unstable political conditions.

Exceptions for Dual Citizenship Through Retention Permits

In certain cases, individuals who do not fall under the aforementioned exceptions may still be allowed to hold dual citizenship by obtaining a special retention permit (Beibehaltungsgenehmigung). This permit allows German citizens to acquire another nationality without losing their German citizenship, provided they can demonstrate a legitimate reason for retaining their German nationality.

Typical reasons for granting a retention permit include professional, economic, or family-related ties to Germany. Applicants must submit a detailed request to the Federal Office of Administration (Bundesverwaltungsamt) outlining their justification for retaining German citizenship while acquiring another nationality.

Dual Citizenship Through Descent

German nationality law also allows individuals to acquire dual citizenship through descent. Those born to a German parent typically acquire German citizenship automatically, regardless of where they are born. If the other parent holds a different nationality, the child may inherit both citizenships.

In some cases, individuals with German ancestry who were deprived of their citizenship due to Nazi persecution may be eligible for reinstatement. The German government has implemented measures to facilitate the naturalization of descendants of victims of Nazi-era citizenship revocations, allowing them to obtain German nationality while retaining their existing citizenship.

Naturalization Without Renouncing Previous Nationality

In some cases, Germany allows individuals to become naturalized citizens without renouncing their previous nationality if their home country does not permit renunciation. Certain countries, such as Iran and Argentina, do not allow their citizens to give up their nationality. In such instances, Germany grants an exception, allowing these individuals to hold dual citizenship.

Moreover, individuals who can prove that renouncing their original nationality would result in excessive hardship, such as financial loss or social disadvantages, may also be permitted to retain both citizenships.

Loss of German Citizenship Due to Acquiring Another Nationality

German citizens who voluntarily acquire the nationality of a non-EU country without obtaining prior approval from German authorities typically lose their German citizenship automatically. This policy prevents individuals from holding dual citizenship unless they have received explicit permission through a retention permit.

However, recent discussions in Germany suggest a possible relaxation of this rule, particularly for those with strong ties to the country. Proposed reforms may allow more individuals to retain their German citizenship while acquiring another nationality.

Benefits and Challenges of Dual Citizenship

Holding dual citizenship in Germany provides numerous advantages, including the ability to live and work freely in multiple countries, access to social benefits, and greater mobility. Dual citizens can also participate in political activities in both countries and benefit from diplomatic protection abroad.

However, dual citizenship also comes with certain challenges. Dual citizens may be subject to taxation and legal obligations in both countries, including mandatory military service in some nations. Additionally, some countries do not recognize dual nationality, which may lead to complications when dealing with legal matters such as inheritance, property ownership, and residency rights.

Future Developments in German Dual Citizenship Law

Germany has been gradually evolving its approach to dual citizenship, reflecting the country’s changing demographics and increasing global mobility. Recent political debates have highlighted the need for more inclusive citizenship laws, particularly in light of Germany’s large immigrant population.

In 2023, the German government proposed further reforms aimed at making it easier for immigrants to obtain German citizenship without renouncing their previous nationality. If these changes are implemented, they could significantly expand access to dual citizenship and enhance Germany’s appeal as a destination for skilled workers and international residents.


Germany’s dual citizenship rules and exceptions reflect a balance between maintaining national identity and accommodating a diverse, globalized population. While the general rule requires individuals to renounce their previous nationality, various exceptions allow many people to retain dual citizenship. Understanding these laws is essential for anyone seeking to navigate the complexities of German nationality regulations. As Germany continues to reform its citizenship policies, the future may bring even greater flexibility for those wishing to hold dual nationality.
