What do I fill out on Form I-9 myself?

On Form I-9, you complete Section One, titled Employee Information and Attestation, while your employer completes a separate section. Form I-9 itself exists to verify your identity and your authorization to work in the United States, and federal law requires it of every employer who recruits, refers for a fee, or hires someone for US employment.

Your part versus the employer’s part

USCIS splits Form I-9 into two sections: Section One, the Employee Information and Attestation, which you complete, and Section Two, the Employer or Authorized Representative Review and Verification, which your employer or their representative handles instead.

Both employees and employers, or an employer’s authorized representative, have to complete their respective parts of the form, since neither section stands in for the other.

Proving who you are

As part of the process, you will need to show acceptable documents that establish your identity and work authorization. A single List A document, such as a US passport, establishes both at once, while a combination of a List B document, like a state driver’s license, and a List C document, like a Social Security card, works too.

What happens after you sign

The employer or their authorized representative has to complete and sign Section Two, which is a review of the documents you provided rather than something you fill out yourself.

Some employers also run E-Verify alongside Form I-9. Participation is voluntary for most employers, though it is required for most companies with federal contracts and in more than 20 states for certain employers.

More questions

Does my employer have a deadline to complete their section?

Yes, an employer must complete Section Two within 3 business days of your first day of work for pay.

Is E-Verify a replacement for Form I-9?

No, E-Verify is not a replacement for Form I-9, a prescreening tool, a background check, or a public registry.

Do I choose which documents to show?

Yes, you can present one List A document, or one document each from List B and List C, depending on what you have available.

Is every Connecticut employer required to use E-Verify?

No, participation is voluntary for most employers, except those with federal contracts or in states that specifically require it.
