Me and my mom sent our Aufenthaltsgestattungs to Auslanderbehorde for an address change one and a half months ago. Hers came back via post a week after of her sending it but mine is still not here. It expires on February 4th and knowing how lengthy paperwork can be in Germany this kinda scares me. Is this normal? When my mom asked our very helpful (!) Social worker about it he just said I dont know and shrugged. What should I do? Who should I contact? Perhaps they sent it and it got lost in the mail, which I want to be informed about.
