Actually, we do not have mandatory detention of asylum seekers. We have a different system.
Persons apply for asylum, and then they are attributed to particular federal states. We have a federal country. They are attributed to a specific federal state. Within this federal state, this person is required to live in a certain area, a certain district. He or she is actually required to live in this particular area. There are criminal law provisions forcing this person to stay there. Social contributions are only paid in this district, which ensures that the person does not travel around Germany. But they are free to move within the area.
