Thank you alot Nilab for the accurate answer to my questions,But what is written on my Duldung ausweis is Erwerbstätigkeit nicht erlaubt.My first question is that while after my daughter is granted National deportation ban by BAMF I'm not still allowed to have work permit?because we have apply multiple times but no answer.secondly before our duration period of our Duldung ausweis was only one month,but after my daughter was granted positive and after we summited our passport to them they change the duration of our Duldung ausweis to 3 months but no working permit on it while?please I will be happy once more if you can give me an answer to this my questions again.Because we went last week to renew our Duldung ausweis it was still the same thing,no working permit on it,and we ask them while they said we must still wait.so I'm really tired and confuse about this because only in my daughter ausweis is stated she can work
