Thanks for the reply. i have already ausbildungsduldung but i found the home and pay by myself the rent. German word WOHNSITZAUFLAGE.
i was before from the goverment accommodation (unterkunft) but now i moved from there and i did not get permission for the (anmeldung) for the new place.
i was yesterday by RATHAUS and the goverment also shared with them that i do not get still the permission for anmeldung so the RATHUAS told me that we will speak with your Landlord (Vermieter).
i am scared that the RATHUAS will tell to my Landlord that i m not allow official to live here,
and second thing that i have ausbildungsduldung according to law 18a after my ausbildung to get aufenthalerlaubnis and also i m in germany from 2013 and in september my 7 years will be completed and from october wil be started my 8th years so hopefully i will be eligible for aufenthalterlaubnis according the german law 25b . is it right ?
