This is the toughest border security and enforcement plan in American history. Those who came here illegally after the December 31, 2011 cut-off date will be deported. The enforcement begins by requiring background checks, proof of gainful employment, and payment of fines and taxes.  However, before undocumented immigrants even get to this step, the border security and fencing plan to achieve 100 percent border awareness and at least a 90 percent apprehension rate must begin implementation. The fine is $2,000, nearly three times what President Obama has pushed for. Immigrants will have to pay taxes and pass repeated background checks for over 10 years before they can apply for legal residents.
