Dear @MCA1986,
Welcome to the Wefugees Community and thank you for reaching out to us.
We discussed similar questions already a few times at this platform. As my colleague explained here, for instance:
"If you have permanent EU residency in Italy (this is called ‘soggiornante di lungo period – CE o UE’), you can enter Germany and apply for a residence permit here.
If you have any other type of permit, you have to first get a visa from the German embassy in Italy."
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
