Dear @Shaheen,
Welcome to the Wefugees Community and thank you for reaching out to us.
The so-called Dublin regulation determines in which European country your asylum case must be processed and it can be quite complicated in practice. As I am not familiar with your individual situation, it is a bit difficult to provide tailored information here. But I can recommend to check Handbook Germany's website which has comprehensive information in various languages for a first overview.
I also highly recommend to get some legal counselling. The "Asylverfahrensberatung" (asylum procedure counselling) can be a good first address. Generally speaking: If you are in Germany and the country being responsible for your case in the first place (according to the Dublin rule) is accepting the German authorities' request to take you back, the German authorities have six months time to deport you to that country. If they can not manage to bring you back within this period, your case may be transferred to Germany. It is important to note that if you hide, for instance, this period can be extended to 18 months. In some cases, it can also make sense to appeal against the Dublin decision. This should be discussed with a lawyer!
I hope these first information are helpful and please don't hesitate to get back to us with any further questions.
All the best,
Meike
