The U.S. Department of Justice's Office of Special Counsel for Immigration-Related Unfair Employment Practices works to prevent employment discrimination based on immigration status or national origin. The document provides examples of discriminatory practices, such as demanding different documents from non-U.S. citizens during the hiring process or terminating workers who receive tentative nonconfirmations in E-Verify on a selective basis. Employers who engage in such discrimination may face civil penalties or be required to pay back pay. Workers who believe they have experienced discrimination are encouraged to contact the OSC Worker Hotline.
