E-Verify: E is for error 54% of the time, study says

E-Verify, the online tool employers can use to check the work-authorization status of new hires, wrongly clears illegal workers about 54% of the time, according to a study commissioned by the Department of Homeland Security. “Many unauthorized workers obtain employment by committing identity fraud that cannot be detected by E-Verify,” said the report by research firm Westat.
