Too late. Those overstays with ability to get status thru family have already been placed in to the citizenship pipeline by Obama.
I know this for a fact because a friend got an UNSOLICITED email from DHS a few weeks offering adjustment of immigration status for his wife.
As someone who has actually issued visas, I can attest to the corruption within ICE. There is a saying within the DOJ about the prosecution of illegals, "It is not over until the illegal alien wins."
Just as happened in 1986, there will be a flood of illegals entering this country to take advantage of an anticipated amnesty. In 1986 the USG estimated that 1 million illegal aliens would apply for amnesty. The true number turned out to be 2.7 million. Imagine if there are far more than the 11 million illegal aliens estimated by the government? It is insane to promise amnesty without knowing the full extent of its impact.
