Dear @Hafiz123,
Thank you for being such an active member of the Wefugee Community!
Regarding your question, which options one have, if the court decides negative on your case: In General, there is the possibility to take the case in the second instance to a court on higher level. However, if this step makes sense should be decided from case to case on an individual basis and I highly recommend to discuss it with a lawyer.
You will find information on the Asylfolgeantrag in a number of threads which have been opened here on the platform in the past. You may have a **** at, for example, the following: https://***.wefugees.de/800324/questions-about-asylfolgeantrag-and-deportation-pakistan or https://***.wefugees.de/800154/it-possible-to-reappeal-after-first-appeal-has-been-rejected.
If I remember correctly, I was mentioning those threads already in an answer on one of your earlier questions. If you need some further information, it might help, if you reformulate or specify your request.
On your third question, I am not sure what exactly you mean with German Certificate. If you could explain again, we would be happy to discuss it.
I hope this helps.
All the best,
Meike
