Dear @mmohamedali,
Unfortunately, people holding a residence permit according to section 104c of the German Residence Act (Chancen-Aufenthalt) are not entitled for family reunification. I am sorry that I can provide any more positive information.
The family reunification options (very limited) with holding a residence permit according to 25b were discussed here before.
In any case, please don’t hesitate to get back to us with any further questions.
All the best,
Meike
