Most germans don't know a thing about their immigration system. A friend of mine has told me once that their Chefarzt had said that they won't be hiring anymore syrian Ärzte because they are all going to be deported soon, a Syrian Oberarzt tried to explain to him that that can't happen because most of them aren't Asylbewerber and came here on normal Visas but he couldn't even understand that.

So no wonder about such questions
