Common Visa Categories for Non-U.S. Employees
As told to Amy White | Reviewed by Canaan Suitt, J.D. | Last updated on April 28, 2025 Featuring practical insights from contributing attorney Tarik H. SultanWith demographic changes, waves of retirements from baby boomers, and a tight labor market, foreign workers are a great way to supplement your existing workforce. When considering a foreign national for employment, seeking the proper visa classification depends upon the type of position being filled and the potential employee’s education and skill level.
The Two Types of Employment-Based Visas
There are two types of employment-based visas:

1. Immigrant Visas
Immigrant visas are sought for the permanent placement of the worker, and confer permanent resident (“green card”) status upon the employee.
In many cases, the employee will work temporarily via a nonimmigrant status while the company pursues permanent resident status for the worker.
2. Nonimmigrant Visas
Nonimmigrant visas are temporary and, with some exceptions, function on the foreign national working for the U.S. employer for a finite period of time.
Nonimmigrant Visa Categories
The U.S. Department of Labor (DOL) lists some 80-plus nonimmigrant categories, with the majority being for temporary employees and their family members. The most common professional work visas include:
- J-1 visa: exchange visitors;
- H-1B visa: specialty occupations that minimally require a bachelor’s degree for entry;
- L-1 visa: intracompany transferee of international organizations;
- O-1 visa: extraordinary ability workers;
- P-1 visa: professional athletes;
- Q visa: cultural exchange visas;
- A or G visa: diplomatic visas;
- E-3, H-1B1, and TN visas: free trade professional visas for Australians; Chileans or Singaporeans; and Canadians or Mexicans, respectively.
You should consult with a seasoned immigration attorney to determine which employment-based visa best fits your company’s particular situation. With the proper guidance, the visa process is less formidable than it appears and can be a great resource for finding untapped talent.
