New Jersey Gov. Chris Christie laid out his plan for immigration reform Saturday while campaigning in New Hampshire.
The GOP presidential hopeful says he wants to track foreign visitors once they enter the U.S. and remind them when their visa has expired.
He says he wants to implement this by using a system similar to the way FedEx tracks a package.
Christie says of the 11 million undocumented workers, 40 percent of them are people who came here on visas and overstayed their visit.
