Trafficking in human beings often affects migrants (both male and female). In Germany, the applicable piece of legislation for entry into the territory, as well as temporary and permanent residence, is the Residence Act [Aufenthaltsgesetz]. Trafficked persons without a residence permit are required to leave the country or may be deported. Fear of having to leave or of being deported often explains why trafficked persons are unwilling to turn to the authorities or to sue their employers.
The three-month reflection and stabilisation period provided for by Section 59 para. 7 of the Residence Act and the temporary residence permit provided for in Section 25 para. 4a is a potential protection mechanism granted to victims of trafficking in human beings.
In the case of EU citizens, however, the Freedom of Movement for EU Citizens Act takes precedence over the Residence Act. In this case, the residence issue is negligible.
You will find more detailed information regarding these pieces of legislation and their implications for trafficked persons in the section on the Residence Act.
