Welcome to the Wefugees Community and thank you for reaching out to us.
Unfortunately, it is hardly possible to predict your chances to get humanitarian protection without knowing your background and your situation better. However, it will be very important to enter the interview at the BAMF (the so-called "Anhörung") as well prepared as possible. The decision on your asylum application will be based on your explanations in this interview. I would highly recommend to get support in a so-called "Asylverfahrensberatung" (asylum procedure counselling services) BEFORE the interview. The local counselling staff may be also able to give you further information on the expected time frame.
The authorities (BAMF) will either grant an asylum or refugee status, subsidiary protection, a ban of deportation or (in the worst case) reject the application. After you received the decision, you may appeal in court as well. Please be aware of the potential narrow appealing deadline.
Regarding the permanent residence permit (Niederlassungserlaubnis), I am afraid that your three years holding a student resident permit before applying for asylum may not be "counted". As far as I know, the student residence permit by itself can unfortunately not qualify for the permanent residence permit. It would be different if you would have finished your studies at a German University/College and you subsequently obtained a residence permit to work. After only 2 years of holding this type of residence permit, people may meet the requirements for the permanent residence already.
The government may oblige asylum seekers to stay in the reception camps for up to 18 months - but this is also dependent on the individual situation.
Dear @mbeon-Christine or @mbeon-fardeen, am I right with my explanations and/or is there anything you would like to add?
For individual counselling you could contact the Refugee Council Mönchengladbach, for instance.
I hope this helps and all the best,
