Am I eligible for RPI immigration visa if I worked illegally?

The great news about the Obama Comprehensive Immigration Reform (officially called as the Border Security, Economic Opportunity, and Immigration Modernization Act of 2013) is that undocumented aliens who worked without authorization using a fake Social Security number or were paid in cash under the table are not going to be penalized for these crimes.  The only problem is if you actually made a false claim to US citizenship after the age of 18.  Other than that, if you worked without papers and paid taxes, you will not be charged with any crimes, and instead, will be approved for a Registered Provision Immigrant (RPI) legal status, that subsequently leads to a green card, and after that naturalization to United States citizen.  If you did not pay taxes, it will not disqualify you either; you will just need to pay all the back taxes before approval.
