I will translate it for you so someone with a good knowledge can help you with your problem,and abviously they don't speak arabic.
The translation is: i live in Hessen and i had my permit residence and i want to move to Berlin, i have a friend in berlin and he got an appartment,and i want to go there and live with him,how can i move to the Berlin job center? And would they give me the permission to stay in Berlin if they knew that i want to live with my friend? Is this possible?.
The problem is (his friend) still taking money from the sozial and the sozial pay the rent for the appartment,and i really don't know what should i do,and if there's anyone who can help me with it and tell me what to do.
