Before you can work in the United States, you — and your employer — must understand your legal work authorization status. US employers are required by law to verify every employee's work eligibility using Form I-9, and unauthorized work carries serious legal consequences for both parties. This guide explains every major pathway to legal work authorization in the US, what to put on your resume, and how immigration changes in 2026 affect job seekers.
Do you need to be a US citizen to work in the United States?
No. You do not need to be a US citizen to work in the US. Legal work authorization comes through multiple pathways — citizenship, permanent residency (green card), and various visa categories. What you must have is one of the following:
- US citizenship (by birth or naturalization)
- US national status (born in American Samoa or certain other US territories)
- Lawful Permanent Resident (LPR) status — a green card
- An Employment Authorization Document (EAD) for certain visa categories
- A work-authorizing nonimmigrant visa (H-1B, L-1, O-1, TN, E-3, etc.)
Employers verify your status using Form I-9, and may use E-Verify — the federal online verification system. Working without authorization is a federal offense and can result in deportation, bars to future US immigration, and criminal penalties.
What is a Green Card?
A green card — officially the Lawful Permanent Resident (LPR) Card — gives you the right to live and work permanently anywhere in the United States for any employer. It is formally known as USCIS Form I-551. Key facts:
- Green cards must be renewed every 10 years using USCIS Form I-90 (the card expires; your status does not necessarily expire)
- With a green card, you can work for any employer in any role — there are no employer sponsorship requirements
- After 5 years of continuous permanent residency (3 years if married to a US citizen), you may apply for US citizenship through naturalization
- Green card holders cannot vote in federal elections and must maintain continuous residence — generally, absences of more than 6 months consecutively can jeopardize your status
- As of May 22, 2026, USCIS significantly restricted Adjustment of Status (AOS) — the process of changing from a nonimmigrant visa to green card status inside the US — shifting most pathways toward consular processing abroad (Sheppard Law, May 2026)
Green card pathways
| Category | Who qualifies | Notes |
|---|---|---|
| EB-1: Priority workers | Extraordinary ability, outstanding professors and researchers, multinational managers | No labor certification required. Fastest employment-based pathway. |
| EB-2: Advanced degree | Masters or higher degree, or exceptional ability | Labor certification (PERM) usually required unless National Interest Waiver (NIW) applies |
| EB-3: Skilled workers | Skilled workers (2+ years training), professionals (bachelor's degree), unskilled workers | PERM labor certification required. Longer wait times, especially for nationals from India and China. |
| EB-5: Investor | Investors committing $1.05M+ ($800k in TEAs) creating 10 full-time US jobs | Investor pathway — significant capital requirement |
| Family-based | Immediate relatives of US citizens (spouses, children under 21, parents) — fastest. Also preference categories for other family members. | Immediate relatives have no annual cap — fastest family route |
| Diversity Visa Lottery | Nationals of countries with historically low immigration to the US — approximately 55,000 visas per year | Cannot apply if from a high-admission country (including Mexico, China, India, Philippines, UK, Canada, El Salvador, Guatemala, Haiti) |
Common US work visas
| Visa | Who it's for | Key features |
|---|---|---|
| H-1B | Specialty occupation workers (bachelor's degree minimum in the field) | Employer-sponsored. Annual lottery cap of 85,000. 3-year initial period, extendable to 6 years. Most common work visa for professionals. |
| L-1 | Intracompany transferees — managers, executives (L-1A) or specialized knowledge workers (L-1B) | Must have worked for the employer abroad for at least 1 year in the preceding 3 years. No annual cap. |
| O-1 | Individuals with extraordinary ability in sciences, arts, education, business, or athletics | No annual cap. High evidentiary standard. Common for outstanding researchers, artists, entrepreneurs. |
| TN (Trade NAFTA/USMCA) | Canadian and Mexican nationals in specific professional occupations | Available only to Canadian and Mexican nationals. Fast processing at ports of entry for Canadians. Annual renewal or 3-year period. |
| E-3 | Australian nationals in specialty occupations | Available only to Australian nationals. 2-year renewable. Annual cap of 10,500 (rarely filled). |
| H-2B | Temporary non-agricultural workers (seasonal hospitality, landscaping, etc.) | Employer-sponsored. Annual cap of 66,000 (with possible supplemental numbers). |
| J-1 | Exchange visitors — students, researchers, au pairs, summer work travel | Programme-specific. Some categories have 2-year home residency requirement before H-1B or green card. |
Employment Authorization Document (EAD)
An EAD — sometimes called a work permit — is a photo ID card issued by USCIS that allows certain visa holders to work in the US for any employer. EADs are available to pending green card applicants (Form I-485), asylum seekers, DACA recipients, F-1 students in OPT or STEM OPT, and certain other categories. Apply using USCIS Form I-765. Note: As of October 30, 2025, the automatic extension of EAD documents upon timely renewal filing ended — check USCIS.gov for current EAD extension rules (USAGov, March 2026).
OPT and STEM OPT — for F-1 students
International students on F-1 visas can work in the US after graduation through Optional Practical Training (OPT):
- Standard OPT: 12 months of work authorization in a field related to your degree
- STEM OPT extension: An additional 24 months (total 36 months) for graduates in STEM (Science, Technology, Engineering, Mathematics) fields at qualifying employers who use E-Verify. STEM OPT is the primary bridge between F-1 and H-1B for international tech graduates.
What to put on your US resume about work authorization
Be clear and honest. Hiring managers need to know if you require sponsorship:
- US citizen or green card holder: No need to mention it — you are automatically eligible. Many candidates add "Authorized to work in the US" for clarity.
- EAD / OPT: "Authorized to work in the US (OPT, valid through [date])" or "STEM OPT authorization through [date]."
- H-1B transfer eligible: "Currently on H-1B — available for immediate H-1B transfer. No cap-gap issue." (Important for employers nervous about timing)
- Requires sponsorship: "Will require H-1B sponsorship" — state this clearly. Many employers won't sponsor and it's better to know early.
