The system Congress and the Obama administration want employers to use to help curb illegal immigration is failing to catch more than half the number of unauthorized workers it checks, a research company has found.
The online tool E-Verify, now used voluntarily by employers, wrongly clears illegal workers about 54 percent of the time, according to Westat, a research company that evaluated the system for the Homeland Security Department. E-Verify missed so many illegal workers mainly because it can't detect identity fraud, Westat said.
“Clearly it means it's not doing its No. 1 job well enough,” said Mark Rosenblum, a researcher at the Migration Policy Institute, a nonpartisan Washington think tank.
