Senate Bill Could Slash Illegal Immigration by 50 Percent: CBO

"A U.S. Senate-passed immigration bill would significantly reduce the flow of illegal immigrants, but increased U.S.-Mexico border security costs would eat into projected budget savings, the Congressional Budget Office said on Wednesday.  The CBO concluded that the bill, which would double the number of federal agents along the border and complete the 700 miles of fencing, would reduce the number of people entering the United States from Mexico without documentation by one-third to one-half." - Reuters, July 3, 2013.
