Employment Authorization: Legal Basis and Categories

Employment authorization in the United States is a legally defined permission that allows noncitizens to work within the country, governed primarily by the Immigration and Nationality Act (INA) and administered through U.S. Citizenship and Immigration Services (USCIS). The framework spans a wide range of immigration statuses — from temporary nonimmigrant workers to lawful permanent residents — each carrying distinct legal bases, documentary requirements, and expiration conditions. Understanding how authorization is categorized, issued, and maintained is essential for compliance with federal employer sanctions law under 8 U.S.C. § 1324a, which prohibits hiring individuals who lack valid work authorization.

Definition and Scope

Employment authorization is the legal right, recognized by federal law, for a noncitizen to accept employment in the United States. This right is not automatic for all visa holders and does not attach to all immigration statuses. The Immigration and Nationality Act, codified at 8 U.S.C. § 1101 et seq., establishes the foundational categories under which authorization may be granted.

USCIS divides employment authorization into two structural categories:

1. Authorization incident to status — Permission to work is inherent in the immigration classification itself. No separate employment authorization document (EAD) is required because the visa category or status already confers the right to work for a specified employer or in a specified field.

2. Authorization that requires a separate document — The individual's underlying status does not automatically permit employment. The noncitizen must apply to USCIS on Form I-765 and receive an Employment Authorization Document (EAD, Form I-766) before beginning work.

The regulatory framework governing these categories is found in 8 C.F.R. § 274a.12, which lists the specific immigration classifications eligible for employment authorization and whether that authorization is automatic or requires application.

How It Works

The mechanism of employment authorization operates through a two-track system tied to the Form I-9 verification process, which all U.S. employers are required by law to complete for every hired employee (USCIS I-9 Central).

Track 1: Status-Based Authorization (Incident to Status)

For noncitizens in this track, employment is authorized by virtue of their visa classification or admission status. The employer verifies work eligibility using the documents that establish the underlying status — such as a visa stamp, I-94 arrival/departure record, or Form I-20. No EAD is required. Examples of classifications that fall under this track include H-1B specialty occupation workers and L-1 intracompany transferees (discussed further under Common Scenarios).

Track 2: Application-Based Authorization

Noncitizens who do not hold a classification that automatically permits work must file Form I-765 with USCIS. The adjudication process typically produces a decision within 90 days under standard processing (USCIS Processing Times). Premium processing is not available for I-765. The resulting EAD is generally valid for up to 2 years depending on the underlying eligibility category, though specific durations are set by regulation.

The USCIS adjudication process for Form I-765 includes:

1. Receipt of the application and fee payment (or fee waiver, where applicable)
2. Biometrics appointment (required for certain categories)
3. Background and security checks coordinated with federal law enforcement
4. Adjudication and issuance of the EAD card, or issuance of a Request for Evidence (RFE) if documentation is incomplete
5. Delivery of the physical EAD card via USPS

Automatic extension rules apply in limited circumstances: under 8 C.F.R. § 274a.13(d), certain EAD holders who timely file for renewal before expiration may continue working during the pendency of the renewal application for up to 180 days.

Common Scenarios

Different immigration classifications produce distinct employment authorization outcomes. The following breakdown covers the most legally significant categories:

Nonimmigrant Visa Classifications (Status-Based)

• H-1B Specialty Occupation (h1b-visa-legal-requirements): Authorization is employer-specific and petition-specific. The worker may only work for the petitioning employer in the approved position. Portability provisions under the American Competitiveness in the Twenty-First Century Act (AC21) allow certain H-1B holders to change employers if a Form I-140 has been approved for at least 180 days.
• L-1 Intracompany Transferee (l-visa-intracompany-transferee-law): Authorized only for the sponsoring employer. L-1A (managers and executives) and L-1B (specialized knowledge workers) carry different evidentiary standards but identical work-authorization mechanics.
• O, TN, E, and Other Nonimmigrant Categories: Each carries employer-specific or activity-specific authorization tied to the petition or admission document.

Status Categories Requiring EAD

• Adjustment of Status Applicants (adjustment-of-status-legal-process): Individuals who have filed Form I-485 (Application to Register Permanent Residence) are eligible for an EAD under 8 C.F.R. § 274a.12(c)(9) while the application is pending.
• Asylum Applicants: Those with a pending asylum application may apply for an EAD 150 days after filing a complete application (INA § 208(d)(2); 8 C.F.R. § 208.7). Authorization is not granted during the first 180-day asylum clock period.
• DACA Recipients (daca-legal-status-and-history): Deferred Action for Childhood Arrivals grants a 2-year period of deferred action and an accompanying EAD under 8 C.F.R. § 274a.12(c)(14). DACA does not grant immigration status; it defers removal and enables work authorization.
• Temporary Protected Status (TPS) (temporary-protected-status-legal-framework): TPS-designated nationals receive automatic work authorization tied to the designation period, renewable through DHS Federal Register notices.
• Spouses of H-1B and L-1 Holders: H-4 spouses of H-1B holders with an approved I-140 or extended H-1B status under AC21 may apply for an EAD. L-2 spouses were found to be employment-authorized incident to status in Shergill v. Mayorkas, 2021 WL 5349806 (W.D. Wash. 2021), a holding USCIS subsequently incorporated into policy.

Lawful Permanent Residents

Green card holders are authorized to work for any employer without restriction, and the green card itself serves as the List A document for Form I-9. Conditional permanent residents (2-year green card holders) carry identical work rights, though they must file Form I-751 to remove conditions before the card expires (green-card-legal-pathways).

Decision Boundaries

The legal distinctions between authorization categories produce concrete compliance boundaries for both employers and noncitizens.

EAD vs. Status-Based Authorization

An EAD holder whose card expires and has no pending renewal has no legal right to continue working, regardless of whether the underlying status is still technically valid. By contrast, a worker authorized incident to status — such as an H-1B holder — may continue working as long as the approved petition period has not expired, even if the visa stamp in the passport has lapsed (a visa stamp is required only for re-entry, not for continued work authorization inside the United States).

Employer Restrictions

Status-based authorization is typically employer-specific. An H-1B worker who leaves the petitioning employer immediately loses authorization with that employer. Self-employment is generally prohibited under H-1B because the worker cannot petition for themselves. An EAD issued to an adjustment of status applicant carries no employer restriction — the holder may work for any employer.

Unauthorized Employment Consequences

Working without valid authorization is a deportability ground under INA § 237(a)(1)(C) and may constitute misrepresentation if the worker falsely claims authorization. Employers who knowingly hire unauthorized workers face civil penalties ranging from $698 to $27,894 per violation as of 2023 (Department of Justice, Office of Special Counsel for Immigration-Related Unfair Employment Practices), with criminal penalties available for pattern-or-practice violations. The removal proceedings legal framework governs enforcement actions against individuals found to be working without authorization.

Document Acceptability

Not all valid immigration documents are acceptable List A documents under Form I-9. An unexpired EAD (Form I-766) qualifies as a List A document. An I-94 showing TPS or DACA status, when combined with the applicable Federal Register notice extending the designation period, may constitute an acceptable List A combination.
