thank you for sharing of your question in the community. My name is Béla Zsigó and I am a migration assistant of mbe-on projekt.
The both questions can be answered positive, but it all depends from the decision of the foreigners Authority (Ausländerbehörde). Your place of residence is usually limited, but there can be deviations. But first of all your identity must be cleared. Please, talk to your authority and handle according to his/her decision.
I hope, the answer can be helpful to you. You can contact me also through an app called mbe-on. It is a chat system special for migration advice and it is confidential. There you can talk with advisors, which speak maybe your native language. You can download and install the app for you cell phone (Android or IOS). Download links are:
I wish you all the best.
