If President Barack Obama’s immigration plan gets past a federal court injunction and 60 percent of illegals apply for deferred action protection under the plan, the U.S. Citizenship and Immigration Services (USCIS) agency projects that it may have to hire an additional 3,100 employees, with a total program cost of up to $484 million a year.

In a detailed response to questions from Republicans on the Senate Judiciary Committee about the cost of processing the illegals at a newly rented facility in Arlington, Va., the USCIS said “planning was based on the assumption that 60 percent of all individuals who may be considered for DACA or DAPA would elect to file a request.”
