The Iowa Civil Rights Act prohibits employment practices that discriminate on the basis of national origin. Practices that discriminate against immigrants legally eligible to work may constitute national origin bias within the meaning of the Act. The Act applies to employers with four or more employees (IA Code Sec. 216.6).
Preemployment Inquiries. 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.
