Germany's immigrants are coming from: Iraq , Afghanistan and Syria
US immigrants combing from : Mexico , El Salvador and Guatemala
Italy is number 3....mostly because it is the closet country to Africa and so therefore they get the brunt of the refugees by ship/boats.
The Germany number stands out like a soar thumb as Merkel is working it overtime.
