Colorado state law also prohibits job discrimination on the basis of national origin. The Colorado Antidiscrimination Act applies to all private employers within the state, to state and local government agencies, and to labor organizations and employment agencies (CO Rev. Stat. Sec. 24-34-402).
Citizenship requirements that are made a condition of employment discriminate on the basis of national origin in violation of the state law. Inquiries about a person's citizenship or country of birth are unlawful and imply discrimination on the basis of national origin.
