Hallo Greetings from Mr Bojang ,
If the BAMF rejects your asylum application, you will be asked to leave Germany.
Refugees who recieve a simple rejection have 30 days to depart or appeal.
You may receive a simple rejection if no other Europeans country is responsible for your asylum application (Dublin regulation) .
The Chances you have is to wait if BAMF will decide to call you for a second interview as the republic of Germany is the only European country responsible for your asylum case .
Mit freundlichen Grüßen
