According to the German Residence Act, valid since January 1, 2005, the residence permit is issued as one of the following:
Residence permit (Aufenthaltsgestattung)
If you apply for refugee status in Germany at the Federal Office for Migration and Refugees (BAMF), you will first receive permission to reside (Aufenthaltsgestattung). This however does not constitute a residence permit. Only once an affirmative decision has been made to accept your refugee claim will you receive a residence permit.
Suspension of deportation (Duldung)
A suspension of deportation (Duldung) is not a proper residence permit. It is issued by the immigration office when deportation has been suspended. It means that the holder must leave Germany, but, for various reasons, he temporarily cannot leave the country or be deported..
If you have permission to reside (Aufenthaltsgestattung) or a suspension of deportation (Duldung) and have found employment, you must immediately apply for a work permit at the immigration office. Your application will be reviewed by the immigration office. The International Placement Services division of the government employment office (Agentur für Arbeit) makes the final decision on whether or not you are allowed to work.
