Hello and welcome to Wefugees. Living together in the family is regulated in Germany with the so-called Familiennachzug. As far as I understand it correctly, in your case it is not possible to claim this right, because it does not provide for a child living abroad to get a residence permit in the country of origin. Unfortunately, we cannot give legal advice here on Wefugees, and I will link our experts @meike and @mbeon-éanna here again. But as far as I know, I would answer your question with a no for now. On this website you can find more information about the family reunion "Familiennachzug":

The website is in several languages. I hope I could help you with my answer and wish you all the best! Please do not hesitate to come back to us with further questions. Saskia
