How will undocumented immigrants be treated before RPI status?

Previously, I analyzed what status undocumented aliens will have before their RPI status is approved under the Comprehensive Immigration Reform bill that would eventually give everyone a Registered Provisional Immigrant (RPI) legal status.  The interesting case is what would happen to all the deportations and removals in process before a person gets legalized but the law is already in place.  Will the American laws be enforced?  The good news is that all you have to do when asked by an officer about your immigration status is that you are eligible for RPI.  There is no need to show any documents or prove that you have even applied.  You cannot be arrested or deported as long as you make this claim.  And if you are still arrested, you can actually sue back the US Government and force American taxpayers to provide you with a free attorney.
