THE COMMENTER WHO SAID, "All you have to do is cut off jobs and benefits and they will leave on their own" is perfectly correct. IT'S CALLED "ATTRITION THROUGH ENFORCEMENT" AND WE DID IT HERE IN AZ FOR 3 YRS. AND LITERALLY HUNDREDS OF THOUSANDS I HAVE READ LEFT THE STATE (I could see the difference and our college kids were now able to get jobs and finish their education! - jobs illegals had stolen!). MAKE THE "E-VERIFY SYSTEM" MANDATORY NATIONWIDE AND WITHOUT A JOB, ILLEGALS WILL LEAVE. THE DIFFERENCE BETWEEN LEGAL ALIENS AND ILLEGAL ALIENS IS THAT LEGAL ONES COME TO BE AMERICAN & IN ANY CASE, AGREE TO RESPECT OUR LAWS. ILLEGALS COME FOR WHAT THEY CAN GET AND HAVE NO RESPECT FOR LAW. THEY COULD HAVE APPLIED BUT PREFERRED NOT TO!
