Can you lose German citizenship by serving in the army of another country?
Yes. In some cases, joining the army or armed forces of another state can lead to the loss of German citizenship, especially if this happens without official permission from the German authorities.
Basic legal rule
According to the German Nationality Act (§ 28 Staatsangehörigkeitsgesetz – StAG), a German citizen may lose their nationality if they voluntarily join the armed forces of a foreign state without having obtained prior consent from the German government.
Situations that may lead to loss of citizenship
Military service in a foreign country without permission
If a German citizen serves in the army of another country without prior approval from the Federal Ministry of the Interior or other competent German authorities, this may be considered a reason for the loss of German citizenship.
Service in a state hostile to Germany
Serving in the armed forces of a country that is hostile towards Germany or represents a threat to Germany is considered an additional, particularly serious basis for loss of citizenship.
Using a foreign nationality in a way that shows allegiance to another state
A person may lose their German citizenship if they use their foreign nationality in a way that demonstrates a special allegiance to another state and thereby harms German interests.
Exceptions and procedures
It is possible to apply for official permission to perform military service in another country before joining.
If this permission is granted, the person does not lose German citizenship through such foreign military service.
The legal assessment is always made on a case-by-case basis, meaning each individual situation is examined separately.
What happens if you lose your citizenship?
You lose the legal protection and benefits associated with German citizenship.
You may face difficulties in travelling to, residing in, or settling long-term in Germany.
Under certain conditions laid down by law, you can apply to reacquire German citizenship.
Important tips
Before joining a foreign army or performing military service for another state, consult the German authorities or a lawyer specialized in migration and nationality law.
Avoid taking decisions that may lead to loss of citizenship without fully understanding the legal and personal consequences.
Summary
Joining the armed forces of a second state without prior permission may result in the loss of German citizenship, especially if the state is hostile to Germany or the service is considered a sign of allegiance to another state.
It is therefore essential to follow the legal procedures and obtain formal approval in advance in order to preserve your German citizenship.
