The repatriation advice office
If you want to leave Germany or have no other option, ask a repatriation advice office. A repatriation advice office will inform you about the next steps. Sometimes a repatriation advice office can also give you money for your journey. The website integplan.de has a list of repatriation advice offices. Sometimes, the Ausländerbehörden try to put pressure on people to leave Germany. In such cases, speak to an independent advice office.
