Introduction: What Is a Work Visa for Migrants in the United States?
A work visa is an official permit issued by the U.S. government allowing foreign nationals to work legally in the country, either temporarily or permanently. These visas are essential to ensure that migrants can contribute to the U.S. economy while complying with immigration laws.
Work visas are issued by the U.S. Department of State and require approval from the U.S. Citizenship and Immigration Services (USCIS), as well as, in many cases, the Department of Labor (DOL).
Depending on the employment objective and the applicant’s situation, work visas are divided into two main categories:
- Temporary Visas: Designed for specific jobs with limited duration.
