"Dreamers, as they have become known, are adults brought here as children who, really, know no other country as a home. They are Americans, if not by birth."
No, they are not.
They are foreign nationals.
The fact that they may have been brought here "at an early age" DOES NOT make them Americans.
They are -- again -- foreign nationals who did not have permission to enter the United States legally.
Otherwise known as... illegal aliens.
