Dear bilal waqas,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
Unfortunately, going to your country of origin and applying for a family reunion visa will be the regular procedure in this matter, as we also discussed, for instance, in this thread.
You will need to give the immigration office (Ausländerbehörde) very good reasons why you actually can not travel back and why they need to make an exception and grant you a residence permit without the visa procedure. As this is a quite difficult process, I would recommend you to seek support by a lawyer in this.
Would you agree dear @manrhei-mbeon or @mbeon-Lena?
Please don't hesitate to get back to us with any further questions.
All the best,
