Registering and using E-Verify in Utah became manadatory for businesses with more than 15 employees on July 1, 2010. This program is to make sure that all employees are legal, it is an easy way to make sure that employeers know who they have hired or are hiring. As long as a business is registered for E-Verify, they can not be liable for the unlawful hiring of an illegal alien as defined in U.S.C. Section 1324a, as long as the business complies with Section 13-47-202. This registration is good for two years.
