Welcome back to the Wefugees Community and thank you for reaching out to us again.
I am also not experienced with the residence permit according to 19d of the German Residence Act. However, I remember that we discussed the family situation in the context of this residence permit once here before.
Then, I will also link two of my colleagues working with mbeon. Dear @mbeon-ruth or @mbeon-fardeen, can @Refusegee reach out to you or can you give any recommendation?
All the best,
