According to the Immigration Reform and Control Act of 1986, which form must be completed by employers and employees?

The Immigration Reform and Control Act of 1986 established requirements for verifying the identity and employment eligibility of individuals hired for work in the United States. Under this law, both employers and employees must complete Form I-9, which is specifically designed for this purpose.

The I-9 form serves to confirm that an employee is legally allowed to work in the U.S. and requires the employee to provide documentation proving their identity and eligibility. Employers are responsible for ensuring that this form is filled out correctly and maintained as part of their records.

The other forms mentioned serve different functions: the W-4 is related to tax withholding allowances, the SS-5 is an application for a Social Security card, and Form I-94 is used to track the arrival and departure of foreign visitors. None of these forms fulfill the requirements set forth by the Immigration Reform and Control Act as effectively as the Form I-9 does.
