Under the Immigration Reform and Control Act, which document serves as evidence of an employee's eligibility?

The original Social Security card serves as evidence of an employee's eligibility under the Immigration Reform and Control Act (IRCA) because this act was designed to verify the employment eligibility of individuals in the United States. Under the IRCA, employers are required to ensure that their employees are legally authorized to work in the U.S.

An original Social Security card is a crucial document because it is issued by the Social Security Administration and contains the individual's Social Security number, which is necessary for tax purposes and ensures they can legally work. This document also helps employers confirm the identity and work authorization of the employee, which is integral to complying with the law.

While a passport, driver's license, and employee ID card can provide personal identification, they do not necessarily establish employment eligibility in the same way or are not specifically intended for that purpose under the requirements of the IRCA. A passport could prove identity and, depending on its category, could show citizenship, but it is not as commonly used in this context as the Social Security card. A driver's license is primarily identification for driving privileges and does not serve as proof of work eligibility. An employee ID card is issued by an employer and does not provide any information regarding the employee's eligibility to work in the United States.
