When hired for a new job, employees are required to prove that they are legally entitled to work in the United States. Employers are required to verify the identity and eligibility to work for all new employees.
An Employment Eligibility Form (I-9) must be completed for all new hires. Employees must provide documentation to prove they are legally entitled to work in the U.S.
The employer must verify the employment eligibility and identity documents presented by the employee and record the document information on the I-9 form.
