Some employers require workers to participate in the federal government's E-VERIFY system. The E-VERIFY computer database compares the new hire's information and documents submitted by the employer to government records to verify that the worker is eligible to work in the U.S.
If the employer receives a positive result for the new worker, the employer knows that worker is properly authorized to work in the U.S.
If the employer receives a negative result, the worker must be contacted in a private setting and allowed 8 business days to resolve the issue (that may require a visit to the local Social Security office).
