Employees are entitled to file a discrimination charge. However if you are presented with documentation that does not reasonably appear to be genuine or to relate to the employee, you may not accept that documentation. While you are not legally required to inform DHS of such situations, you may do so if you choose. However, DHS is unable to provide employment eligibility verification services other than through its E-Verify program. If you treat all employees equally and do not single out employees based on their national origin or citizenship status for closer scrutiny, you are unlikely to be found to have engaged in unlawful discrimination.
