Dear
@Godswill,
thank you for your question and contribution to our vibrant community.
As for your question:
The Berufung (2nd appeal) is at the lower court the last appeal you can make if you still get a rejection( affirming the last decision of the court) then you can go to the higher court or proceed through the so called Härtfallkommssion(depending which city you are living) and seek a political decision on your right to stay in Germany. In that case please refer the question in the community with the city and we will look for the contact details for you.
Good luck with the appeal and if any other questions arise please feel free to use the community,
Best regards,
Nilab
