Get RPI status if arrived after cutoff date passed

Like any other immigration amnesty, the Obama Immigration Reform has a cut off deadline of 31st December in the year 2011.  Whether you entered the country legally or simply crossed the border illegally by foot from Mexico, you will need a pretty reliable evidence of being in the US on or before that date.  What if you came after that date?  It seems it will be impossible to legalize to Registered Provision Immigrant (RPI) legal status under the Border Security, Economic Opportunity, and Immigration Modernization Act of 2013 (BSEOIM).  But, there is no need to worry that demand for undocumented workers is going away.  On the contrary, as legalized immigrants fight for high paying jobs, there will be a lot more openings for employees without papers willing to work for low wages, simply because American employers are addicted to cheap labor and will not be able to afford higher wages that legal workers will demand.  The only downside that you will continue to be an illegal immigrant till the next amnesty is passed, which will be sooner than this one, because as more immigrants become citizens, they will have a lot more political clout.
