Dear @Obumkelly79,
Welcome back to the Wefugees Community and thank you for your question.
I assume you are referring to the so-called "Fachkräfteeinwanderungsgesetz" which was implemented last year?
You may find more details and the visa application process for qualified nurses on this website, for instance.
I hope it helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
