Clearly you have absolutely no idea what the currents immigration stats look like the last 3 years do you?
People really need to get a clue about this. Obama has broken all deportation records for Presidents, but people still insist hes the worst President ever when it comes to immigration/immigration enforcement. Hes not the worst, and based on the states of deportations, he out ranks everyone.
The fact of the matter is, the USCIS and the justice system do not have the money or the man power to deal with illegal immigration. I personally believe, utilizing current resources to deport illegal aliens who have committed crimes is a good policy. You cannot humanly possible deport everyone, prioritize the extremely bad ones and get them out. If there are resources left over, then go after the rest.
What needs to be done is sealing the border. Its impossible with out spending tons of money, but it is more practical/affordable than trying this mass deportation crap.
