Thank you for reaching out to the Wefugees community.
I have a question: Do you mean § 19a Aufenthaltsgesetz? With this paragraph you get a stay as a qualified specialist (blue card).
Please answer me, so I can give you more informations.
I would be very happy if you would contact me again with further questions. I'm a consultant with mbeon and I‘ll be glad to help you over a longer period of time. Mbeon is an online advice for migrants via the mbeon app, which you can install on your smartphone for free. Download it from App Store or Google Play Store. You can find me in the mbeon app and get confidential individual advice in a secure virtual space without other people reading our conversation. Further information: www.mbeon.de.
