What Is Work Authorization?
Key Takeaways
- ✓Work authorization is the legal right to be employed in a specific country. In the US, every worker must prove work authorization through the Form I-9 process, regardless of citizenship or national origin.
- ✓US citizens and permanent residents have permanent work authorization. Foreign workers on visas (H-1B, L-1, O-1, TN, etc.) have time-limited authorization tied to their visa status and employer sponsorship.
- ✓Employers must verify work authorization for every new hire using Form I-9. Failing to complete I-9s or knowingly hiring unauthorized workers results in civil and criminal penalties.
- ✓Employers cannot discriminate based on citizenship status or national origin during the verification process. Asking for specific documents, refusing valid documents, or only verifying certain employees violates anti-discrimination law.
- ✓Work authorization verification is separate from E-Verify. Form I-9 is mandatory for all employers. E-Verify is mandatory only for federal contractors and employers in states with E-Verify mandates.
Work authorization sits at the intersection of immigration law and employment law. For HR teams, it boils down to one obligation: verify that every person you hire has the legal right to work in the United States. Do it for every hire, do it consistently, and don't discriminate in the process. The Form I-9 is the vehicle for this verification. The employee presents identity and work authorization documents from the List of Acceptable Documents. The employer examines them, confirms they appear genuine and relate to the person presenting them, and completes the form. That's it. Employers aren't immigration officers. They're not expected to detect sophisticated forgeries. But they must conduct the verification in good faith and treat all employees equally. Where it gets complicated: the growing use of foreign worker visa categories (H-1B, L-1, OPT, TN) means HR teams frequently manage work authorization timelines, visa expiration dates, and reverification requirements for employees whose authorization is temporary.
The Form I-9 Verification Process
Form I-9 has strict timing requirements and documentation rules. Errors are the most common cause of employer penalties.
Section 1: Employee information (completed by employee)
The employee completes Section 1 on or before their first day of work. They attest to their citizenship or immigration status: US citizen, noncitizen national, lawful permanent resident, or alien authorized to work. Employees who are authorized to work with an expiration date must provide the expiration date and their USCIS number, I-94 number, or foreign passport number. The employee signs under penalty of perjury. Employers can't pre-populate Section 1 or tell the employee what to write, but they can help employees who need assistance completing the form.
Section 2: Employer verification (completed by employer)
Within 3 business days of the employee's start date, the employer examines the employee's documents and completes Section 2. The employee chooses which documents to present from the List of Acceptable Documents: one List A document (which proves both identity and work authorization), OR one List B document (identity) plus one List C document (work authorization). The employer records the document title, issuing authority, number, and expiration date. The employer must physically examine original documents (photocopies aren't acceptable for examination, though employers may keep copies). For remote hires, the employer must arrange for an authorized representative to examine documents in person.
Section 3: Reverification and rehires
When an employee's work authorization expires (for those with time-limited authorization), the employer must reverify before the expiration date using Section 3. Only work authorization documents are reverified, not identity documents. For rehires within 3 years of the original I-9 date, the employer can either complete Section 3 of the existing I-9 or start a new I-9. Employers cannot reverify US citizens, US nationals, or lawful permanent residents who present a List B document with an expiration date. Over-reverification of these categories constitutes citizenship or national origin discrimination.
Common US Work Visa Categories
HR teams working with foreign national employees need to understand the major visa categories and their employment implications.
| Visa | Category | Typical Duration | Employer Sponsorship Required | Key Restrictions |
|---|---|---|---|---|
| H-1B | Specialty occupation | 3 years, extendable to 6 | Yes | Employer-specific; must file LCA; annual cap of 65,000 (plus 20,000 for US master's) |
| L-1A/L-1B | Intracompany transferee | L-1A: 7 years; L-1B: 5 years | Yes | Must have worked for related company abroad for 1+ year |
| O-1 | Extraordinary ability/achievement | 3 years, extendable | Yes (petitioner) | Must demonstrate extraordinary ability through evidence of sustained national/international acclaim |
| TN | USMCA professionals (Canada/Mexico) | 3 years, renewable | Employer letter required | Limited to specific professional categories listed in USMCA |
| F-1 OPT | Post-graduation work (students) | 12 months (36 for STEM) | E-Verify enrollment required for STEM extension | Must be related to field of study; STEM extension requires E-Verify |
| H-2B | Temporary non-agricultural | Up to 1 year, extendable to 3 | Yes | Seasonal/temporary need must be demonstrated; annual cap of 66,000 |
| EAD (various) | Employment Authorization Document | Varies by underlying status | Depends on category | Tied to pending applications, asylum, TPS, or other qualifying status |
Anti-Discrimination Rules in Work Authorization Verification
The Immigration and Nationality Act (INA) prohibits discrimination in the I-9 and hiring process. These rules are enforced by the Department of Justice's Immigrant and Employee Rights Section (IER).
Document abuse
Employers cannot request specific documents or more documents than the I-9 requires. If an employee presents a valid driver's license (List B) and unrestricted Social Security card (List C), the employer must accept them. Asking for a passport instead, requesting a green card, or saying 'I need to see your work permit' when the employee has already provided valid List B + C documents is document abuse. Penalties range from $2,000 to $5,000 per violation for first offenses.
Citizenship status discrimination
Employers with 4 or more employees cannot discriminate based on citizenship or immigration status in hiring, firing, recruitment, or referral for a fee. This means an employer can't refuse to hire a work-authorized noncitizen in favor of a citizen, require different documents for noncitizens, or fire an employee because their work authorization has an expiration date (as long as they're currently authorized).
National origin discrimination
Employers with 4 to 14 employees are covered by INA anti-discrimination provisions (employers with 15+ are covered by Title VII). You can't verify I-9 documents only for employees who 'look foreign,' speak with accents, or have non-English names. The verification must be uniform across all new hires. Selective verification is a red flag that triggers IER investigations.
Work Authorization Violation Penalties
Penalties are assessed per violation and escalate for repeat offenses. Both paperwork errors and substantive violations carry consequences.
| Violation | First Offense | Second Offense | Third+ Offense |
|---|---|---|---|
| I-9 paperwork violations (missing/incomplete forms) | $272-$2,701 per form | $272-$2,701 per form | $272-$2,701 per form |
| Knowingly hiring/continuing to employ unauthorized workers | $676-$5,404 per worker | $5,404-$13,508 per worker | $8,106-$27,018 per worker |
| Document fraud (I-9, I-551, etc.) | Up to $5,000 fine and/or 5 years imprisonment | Up to $10,000 fine and/or 10 years imprisonment | Up to $25,000 fine and/or 15 years imprisonment |
| Discrimination (document abuse, citizenship, national origin) | $2,000-$5,000 per individual | $5,000-$10,000 per individual | $10,000-$25,000 per individual |
| Pattern or practice of hiring unauthorized workers | Criminal penalties: up to $3,000 per worker and/or 6 months imprisonment | Enhanced penalties | Enhanced penalties |
Preparing for an I-9 Audit (ICE Inspection)
Immigration and Customs Enforcement (ICE) conducts worksite inspections. Being prepared means being audit-ready at all times, not scrambling when the Notice of Inspection arrives.
- ICE serves a Notice of Inspection (NOI) giving the employer 3 business days to produce all I-9 forms. Some employers receive as little as 24 hours in exigent circumstances.
- Conduct internal I-9 audits annually. Review every form for completeness: Section 1 fully completed, Section 2 completed within 3 business days, documents properly recorded, all signatures present, reverifications completed on time.
- Correct errors when you find them. Draw a single line through the error, enter the correct information, initial and date the correction. Don't use white-out. Don't backdate. Don't create new I-9s for existing employees (use Section 3 for reverification).
- Store I-9s in a dedicated file separate from personnel files. ICE can inspect I-9s without accessing other employee information, and having them in a separate system speeds up the audit response.
- Keep I-9s for 3 years after hire date or 1 year after termination, whichever is later. Destroying I-9s too early is itself a violation. Keeping them too long is also a risk because old I-9s with errors become audit findings.
- Designate a single point of contact for ICE audits. Train this person on response procedures, including what to say (and not say) to ICE agents.
Work Authorization Verification for Remote Employees
Remote hiring creates I-9 challenges because the employer must physically examine original documents. Here's how to stay compliant.
Authorized representative
An employer can designate an authorized representative to examine I-9 documents on their behalf. This can be anyone: a notary, an accountant, a friend of the employee, even a family member. The representative examines the original documents, completes Section 2, and sends the form to the employer. The employer remains liable for any errors the representative makes, so providing clear instructions and a checklist is essential.
DHS alternative procedure (post-COVID)
During COVID-19, DHS allowed virtual document examination (video call or fax/email). This flexibility was extended multiple times and eventually became a permanent alternative procedure in August 2023 for E-Verify employers. Under the alternative procedure, E-Verify employers can examine documents remotely via video call and retain copies. The employee must present original documents in person within 3 business days of the virtual examination if the employer requests it. Non-E-Verify employers must still use in-person examination.
