Every U.S. employer is legally required to verify the identity and work authorization of each person they hire. This is done using Form I-9, a critical document that must be properly completed, stored, and made available for inspection upon request. Whether you run a small business or manage compliance for a large organization, following I-9 rules is essential to avoid costly penalties.

Our business immigration attorneys work with employers across industries to implement strong I-9 policies, correct errors, and stay prepared for audits. We help protect your business by making sure your hiring practices meet all federal requirements.

What Is I-9 Compliance?

Form I-9 is used to verify the identity and employment eligibility of every person hired for a job in the United States. All U.S. employers, regardless of size, must ensure that:

  • Section 1 is completed by the employee on or before the first day of work, and
  • Section 2 is completed by the employer within three business days of the hire date.

The employer must review the employee’s documents in person (or through an approved remote process) and ensure that the documents reasonably appear to be genuine and relate to the person presenting them.

Why I-9 Compliance Matters

Proper I-9 compliance protects your business from legal and financial risk. A single audit can expose years of errors, leading to:

  • Hefty civil fines for paperwork mistakes or unauthorized hires
  • Criminal penalties for knowingly hiring undocumented workers
  • Debarment from federal contracts
  • Reputational damage that affects public perception and investor confidence

Strong I-9 policies also help streamline HR operations, improve consistency across locations, and reduce risk during acquisitions or regulatory audits.

Who Needs to Complete Form I-9?

Every paid employee working in the United States must complete Form I-9, regardless of citizenship or immigration status. This includes U.S. citizens, green card holders, and foreign nationals with work authorization.

You do not need to complete Form I-9 for:

  • Independent contractors
  • Volunteers
  • Casual domestic workers not working on a regular basis

However, employers are still responsible for ensuring that individuals hired through staffing agencies or subcontractors are properly documented. In some cases, the liability for noncompliance may still fall on the primary employer.

I-9 Form Retention and Storage Requirements

Employers must retain Form I-9s for three years after the date of hire or one year after the employee’s termination, whichever is later. Forms can be stored:

  • On paper
  • In a secure digital system
  • On microfilm or microfiche

However, they must be readily available within three business days if requested by federal agencies like the Department of Homeland Security (DHS), Department of Labor (DOL), or Department of Justice (DOJ). Failure to produce forms in time can result in penalties, even if the forms are otherwise correct.

What Happens During an I-9 Audit?

I-9 audits are typically initiated by Immigration and Customs Enforcement (ICE) or the Department of Labor through a Notice of Inspection (NOI). Employers must produce all requested I-9 forms within three business days of receiving the notice.

During the audit, investigators may:

  • Review forms for accuracy, timeliness, and completion
  • Identify missing or incorrect documents
  • Issue Notices of Suspect Documents or Notices of Technical Violations
  • Request follow-up interviews or site visits

At the conclusion of the audit, ICE may issue a Notice of Intent to Fine (NIF) if violations are found. Employers often have a limited window to correct certain technical errors, but not all mistakes are fixable after the fact.

Common I-9 Mistakes

Many employers make I-9 errors without realizing it. Some of the most common include:

  • Completing Section 1 late or without signatures
  • Accepting invalid or expired documents
  • Using the wrong document combinations (e.g., two List B items)
  • Failing to reverify work authorization for temporary visa holders
  • Correcting mistakes improperly—e.g., erasing or white-out instead of proper annotation
  • Keeping I-9s in unsecured or disorganized storage
  • Inconsistent processes across locations or departments

These errors can lead to fines even if all employees were legally authorized to work.

FAQs About I-9 Compliance

What documents can be accepted for I-9 verification?

Acceptable documents include U.S. passports, permanent resident cards, driver’s licenses with Social Security cards, and other forms listed on the official I-9 instructions. The employee chooses which documents to present.

What if an employee presents fake documents?

If you have reason to believe a document is fake or doesn’t belong to the employee, you must not accept it. Consult an attorney immediately to avoid discriminatory practices or legal violations.

Are we required to use E-Verify?

Most employers are not required to use E-Verify, but some government contractors and state employers must. E-Verify can be a useful compliance tool if used correctly.

How do we fix a mistake on an I-9?

Make a single-line strikeout, write the correction, and initial and date it. Never erase or overwrite information. Always document who made the correction.

Do remote employees follow the same verification rules?

Yes, but employers must follow DHS guidance for remote verification or designate an authorized representative to complete Section 2 in person.
