Yea, in the Detroit area they are crawling all over each other like ant. Once they get a toehold they take over the town. Remeber Bagwan Shreragnesh in Antelope, Oregon. It nearly took an act of congress to evict the bastards. They made life hell for the inhabitants (American) of Antelope. No longer is there a melting pot in America where immigrants insinuate themselves into American life. Now it is Balkanization. America is a mosaic of different cultures which will be at each others throats if immigration reform isn't enacted, and quick.
The guy with the Cadillac and all the women in the orange robes?
Balkanization will probably happen, just like big city ethnic neighborhoods only on a greater scale. Whole cities, not just neighborhoods if things go unchecked. I don't look for anything to be done on immigration reform unless we're attacked again.
