Sen. Rand Paul (R-Ky.)  introduced an amendment Thursday to the Senate immigration bill that would effectively strip the bill's path to citizenship and require illegal immigrants to apply through regular channels.

The "No New Pathway to Citizenship Act" amendment would allow illegal immigrants to remain in the United States as Registered Provisional Immigrants — a new work visa category — but force them to apply as though they were still in their home country.
