The Ultimate Guide to U.S. Work Visas and Employment Green Cards


Looking to work legally in the U.S.? Whether you’re coming for a short-term job or aiming for permanent residence, here’s a breakdown of the most common nonimmigrant work visas and employment-based green card categories.

🛂 Temporary (Nonimmigrant) Work Visas – Working in the U.S. for a Limited Time or Status while Awaiting Green Card

What Is a Nonimmigrant Visa? 🛂

A nonimmigrant visa lets you come to the U.S. temporarily for a specific purpose—like work, study, tourism, or medical treatment. These visas do not lead directly to a green card or permanent residency. Each visa has its own rules about how long you can stay and what you’re allowed to do while you’re here. Common examples include H-1B (for skilled workers), F-1 (for students), and B-2 (for tourists).

If you’re planning to work in the U.S. for a limited time, a nonimmigrant visa is the first step.

The following visas let you work in the U.S. for a specific employer for a limited period of time:

  • H-1B – Specialty Occupations
    For professionals with at least a bachelor’s degree (common in tech, finance, engineering). Employer sponsorship required.
  • L-1 – Intra-Company Transfer
    For employees of international companies transferring to a U.S. branch (executives, managers, or specialized workers).
  • O-1 – Extraordinary Ability
    For individuals with exceptional talent in sciences, arts, education, business, or athletics.
  • TN – NAFTA/USMCA
    For Canadian and Mexican citizens working in specific professions under treaty agreements.
  • E-2 – Treaty Investor/Employee
    For citizens of treaty countries who invest in or work for a business in the U.S.
  • E-3 – Australian Specialty Occupations
    Like the H-1B, but exclusively for Australian nationals.
  • H-2A – Agricultural Workers
    Seasonal or temporary farm workers.
  • H-2B – Non-Agricultural Workers
    For seasonal jobs like hospitality, landscaping, and construction.
  • R-1 – Religious Workers
    For ministers and religious professionals.
  • J-1 – Exchange Visitors
    Covers internships, research, teaching, au pairs, and more (with possible work authorization).

🟩 Employment-Based Green Cards (Permanent Residence)

These visa/green card petitions allow you to live and work permanently in the U.S., usually with employer sponsorship:

EB-1 – Priority Workers

  • Individuals of extraordinary ability (no employer needed)
  • Outstanding professors or researchers
  • Multinational executives and managers

If the applicant is inside the U.S., then the EB-1 category allows the applicant to file for the green card/adjustment of status concurrently with the visa petition as long as the applicant has a nonimmigrant visa or legal nonimmigrant stay status in the U.S. at the time of filing.

EB-2 – Advanced Degree Professionals / Exceptional Ability

  • Requires PERM labor certification + job offer
  • National Interest Waiver (NIW) option allows self-petition

The EB-2 Visas currently have a wait list for approximately 2–3 years from the process start date.

EB-3 – Skilled Workers, Professionals, and Other Workers

  • Requires job offer and PERM
  • Includes nurses, teachers, and skilled trades

The EB-3 Visas currently have a wait list for approximately 4.5–6 years from the process start date.

EB-4 – Special Immigrants

  • Religious workers [only for Ministers now], SIJS (juveniles), international organization employees, etc.

EB-5 – Immigrant Investors

  • Invest $800K–$1.05M in a U.S. business that creates 10+ jobs

The EB-5 Immigrant Investor Visa provides a conditional (2-year) green card to applicants initially, and requires filing for removal of conditions (via USCIS Form I‑829) after 2 years.

The removal of conditions for the EB-5 based green card to receive a 10-year green card requires the showing of the following to USCIS:

  • The investment was sustained over the 2-year period
  • The required number of 10 full-time U.S. jobs were created or will be created within a reasonable time
  • The capital remained at risk and in the new commercial enterprise
  • Active day-to-day management is not required if the investor is involved in policy formulation (e.g., as a limited partner)
