E-Verify is an Internet-based, free program run by the United States government that compares information from an employee's Employment Eligibility Verification Form I-9 to data from U.S. government records. If the information matches, that employee is eligible to work in the United States. If there is a mismatch, E-Verify alerts the employer and the employee is allowed to work while he or she resolves the problem; they must contact the appropriate agency to resolve the mismatch within eight federal government work days from the referral date. The program is operated by the Department of Homeland Security (DHS) in partnership with Social Security Administration.
According to the DHS website, more than 353,000 employers now use E-Verify. Over 1,400 companies enroll in the program every week. According to DHS, in 2011 a random sample of E-Verify users was surveyed on satisfaction with the program. DHS called the results "outstanding" noting that E-Verify received an overall customer satisfaction rating of 85, which is "based on the American Customer Satisfaction Index (ACSI), the national indicator of customer evaluations of the quality of goods and services available to U.S. residents." DHS notes that E-Verify’s score of 85 is a three point increase from the 2010 survey and that E-Verify is "a trailblazer when compared to its federal government counterparts" because "E-Verify’s score is 20 points above the current federal government average."
