German Dual Citizenship Rules

Dual citizenship has become one of the most discussed topics among expats living in Germany.

For many years, applicants seeking German citizenship were often required to renounce their previous nationality. Recent legal reforms have significantly changed the situation and made dual citizenship possible for a much larger number of people.

This guide explains how German dual citizenship works, who may benefit from the new rules, and what applicants should know before applying for naturalization.

What Is Dual Citizenship?

Dual citizenship means a person legally holds citizenship in two countries at the same time.

A dual citizen may:

• Hold two passports
• Enjoy rights in both countries
• Live and work in either country, subject to local laws
• Access services and benefits available to citizens

However, dual citizenship can also create obligations in multiple jurisdictions.

Has Germany Changed Its Dual Citizenship Rules?

Yes.

Germany has introduced reforms that significantly expanded opportunities for dual citizenship.

As a result, many applicants who previously would have been required to give up their original nationality may now be able to retain it while becoming German citizens.

These changes have made German citizenship more attractive for skilled workers, international professionals, and long-term residents.

Who Can Benefit From Dual Citizenship?

Potential beneficiaries include:

• Long-term foreign residents
• Skilled workers
• EU citizens
• Family members of German citizens
• Blue Card holders
• International professionals
• Foreign students who later settle in Germany

Each application is assessed individually.

Can I Keep My Original Nationality?

In many situations, yes.

However, applicants should always verify:

• German citizenship rules
• Rules of their current nationality
• Potential consequences under the laws of their home country

Some countries allow dual citizenship without restrictions, while others may impose limitations.

Applicants should review the laws of both countries involved.

Dual Citizenship and Naturalization

Applicants seeking German citizenship through naturalization must still satisfy all standard requirements.

These generally include:

• Legal residence in Germany
• Language requirements
• Financial stability
• Integration requirements
• Commitment to Germany's constitutional order

For a complete overview, see our guide on German Citizenship Requirements.

Dual Citizenship Through Marriage

Marriage to a German citizen does not automatically grant dual citizenship.

Applicants must still complete the naturalization process and satisfy legal requirements.
