The Form I-9 Employment Eligibility Verification is a document used to confirm that an individual is allowed to work in the United States. Employers will verify the employability and identity of all potential employees, both citizens and noncitizens, by reviewing ID and employment documentation before completing Form I-9.

When to Use

Employers are required to provide all employees with Form I-9 after a job offer is made. Employee can be defined as any person hired to perform labor or services in exchange for compensation in the United States. Employers must also make the Instructions for Form I-9 available so employees can reference it while completing their portion of the form.

How to Fill Out


Once provided with a copy of Form I-9, an employee must complete Section 1 of the form no later than the first day of employment. This section asks for the following personal information:

  • Full name
  • Address of residence
  • Date of birth
  • Social Security Number
  • Email address
  • Phone number
  • Citizenship/immigration status
  • Noncitizen number (if applicable)
  • Signature
  • Date


Within three business days after the employee’s first day of employment, the employer must complete Section 2 of the form. This portion of the form describes the type of identification and employment authorization documents the employee provided. The employer must also provide their full name, their signature, the signing date, the name and address of the entity, and the employee’s first day of work.

Supplement B (page 4) only needs to be completed when the employer is required to reverify an employee’s employment authorization documents or rehire the employee within three years of the first Form I-9 being completed. (More details on these requirements can be found in the instruction forms.)

Translators (If Applicable)

Supplement A (page 3) of the form must be completed by any preparer or translator who helped the employee complete this document.

After Completion

Form I-9 does not need to be filed with the United States Citizenship and Immigration Services (USCIS). Instead, employers are asked to maintain copies of every employee’s Employment Eligibility Verification form in the event a government official requests it. Records are to be kept for three years from the hiring date or one year after termination, whichever is later.
