Form I9, officially titled the Employment Eligibility Verification form, is a mandatory document required by U.S. Citizenship and Immigration Services (USCIS) for all employers hiring individuals to work in the United States. Both the employee and employer must complete specific sections of the form I9 within three business days of the employee's start date. It serves as legal proof that the employer has verified the worker's identity and employment authorization.
The form consists of three sections: Section 1 is completed by the employee on their first day, providing personal information and attesting to their work authorization status. Section 2 is completed by the employer within three business days, documenting the review of original identity and employment authorization documents such as a passport, driver's license combined with Social Security card, or permanent resident card. Section 3 is used for reverification or rehires. For example, when a manufacturing company hires a new production worker, HR must physically examine acceptable documents, record details on the form I9, and retain it for either three years after hire or one year after termination, whichever is later.
Form I9 compliance is critical because employers face severe penalties for violations, ranging from $272 to $2,701 per form for paperwork errors, and $573 to $22,927 per unauthorized worker for knowingly hiring individuals without work authorization. Beyond legal consequences, proper form I9 management protects organizations from Immigration and Customs Enforcement (ICE) audits and potential criminal charges. The verification process ensures a legally authorized workforce while demonstrating an employer's commitment to following federal immigration laws. Maintaining accurate I9 records also streamlines government audits and reduces operational risk during mergers, acquisitions, or compliance reviews.
- Provide form on or before day one: Give new hires Form I9 at or before their employment start date. Employees must complete Section 1 by the end of their first day of work, attesting to their employment authorization status and providing required personal information.
- Examine original documents: Within three business days of the hire date, physically inspect original, unexpired documents from the acceptable documents list. Choose either one List A document (proving identity and work authorization) or one List B (identity) plus one List C (work authorization) document.
- Complete employer section: Record document titles, issuing authorities, numbers, and expiration dates in Section 2. Sign and date the form, certifying that documents appear genuine and relate to the employee. Never specify which documents an employee must present.
- Retain and reverify: Store completed forms separately from personnel files for three years after hire or one year after termination, whichever is later. Use Section 3 to reverify work authorization for employees with expiring documents or when rehiring within three years.
Key Statistics & Benchmarks
- All U.S. employers must complete Form I9 — regardless of company size or number of employees hired.
- Penalties range from $272 to $22,927 per violation — depending on offense severity and repeat violations.
- ICE conducted over 6,000 I9 audits in 2018 — resulting in millions in fines for non-compliant employers.
- Forms must be retained for 3 years after hire — or 1 year after termination, whichever date is later.
Common Mistakes to Avoid
- Completing Section 2 late: Employers must finish document verification within three business days of the hire date, not the offer date.
- Accepting photocopies or expired documents: Only original, unexpired documents from the acceptable lists are valid for I9 verification purposes.
- Specifying which documents to present: Employees choose which acceptable documents to provide; employers cannot require specific documents like passports or green cards.
Frequently Asked Questions
What is Form I9 and who needs to complete it?
Form I9 is the Employment Eligibility Verification form required by federal law for every person hired to work in the United States, regardless of citizenship status. Both the employee and employer must complete designated sections of the form. Employees fill out Section 1 on their first day, while employers complete Section 2 within three business days after examining original identity and work authorization documents. All U.S. employers must use Form I9, with no exceptions based on company size or industry.
How do I properly complete Form I9?
Employees complete Section 1 by the end of their first work day, providing personal information and attesting to work authorization. Employers then examine original documents from the acceptable lists—either one List A document or one List B plus one List C document—and complete Section 2 within three business days. Record document details accurately, sign, date, and retain the form for three years after hire or one year after termination, whichever is later. Never accept photocopies or specify which documents employees must present.
What documents are acceptable for Form I9 verification?
List A documents establish both identity and work authorization, including U.S. passports, permanent resident cards, and employment authorization documents. List B documents prove identity only, such as driver's licenses, state IDs, or school IDs with photographs. List C documents establish work authorization only, including Social Security cards and birth certificates. Employees present either one List A document or one from List B combined with one from List C. All documents must be original and unexpired.
Can I complete Form I9 electronically or remotely?
Yes, employers may use electronic I9 systems that meet regulatory requirements for security, audit trails, and electronic signatures. During COVID-19, USCIS introduced temporary flexibility allowing remote document inspection via video, though this has since expired. Under standard rules, employers must physically examine original documents in the employee's presence. Electronic systems streamline storage, tracking, and reverification but don't eliminate the requirement for in-person document inspection unless specific alternative procedures are authorized by USCIS.
