It's been set aside for now.
Nothing will be done about illegal immigration UNTIL illegals start running for political office.
Illegals can work for low paying jobs because they do not have to pay for housing, health care, food, education, energy, etc. like legal citizens have to. Legal citizens cannot afford to live on the low wages offered to illegals, and thus cannot work the jobs that illegals do. Add up the average cost of living in the US, and compare this to what the average illegal makes.
BTW, how many countries offer free services to illegal Americans?
