Final answer:
A U.S. military card is a valid List C document for Form I-9 that verifies a candidate's identity and work eligibility. The Immigration Reform and Control Act of 1986 requires employers to validate such documents while avoiding hiring illegal immigrants and discriminatory hiring practices.
Step-by-step explanation:
The document from List C that verifies a potential candidate's identity and right to work for Form I-9 is a U.S. military card. Under the Immigration Reform and Control Act of 1986, employers are required to confirm and document the identity and employment eligibility of their employees.
The act prohibits the hiring of illegal immigrants and mandates that employers ask for proof of citizenship or eligibility to work in the U.S. A U.S. military card satisfies the requirement for proving both identity and work eligibility and is considered a valid document for Form I-9 purposes. It is important to note that in order to comply with the law, employers must also avoid discriminatory practices during the hiring process, such as asking illegal interview questions regarding national origin or citizenship that are not related to job requirements.
