Title VII of the Civil Rights Act of 1964 (“Title VII”) prohibits discrimination in hiring, promotion, discharge, pay, and other aspects of employment, on the basis of race, color, or national origin
Employers are also prohibited from discriminating because of citizenship status against U.S. citizens, U.S. nationals, and the following classes of aliens with work authorization: permanent residents, temporary residents (that is, individuals who have gone through the legalization program), refugees, and asylees. However, foreign nationals and their potential employers should be aware that there are U.S. immigration regulations associated with both employment and volunteer opportunities. The unlawful employment of foreign nationals by U.S. employers is a violation of federal law and can subject employers to both civil and criminal penalties.
