Work Authorization

The United States welcomes thousands of foreign workers in multiple occupations or employment categories every year. These include artists, researchers, cultural exchange participants, information technology specialists, religious workers, investors, scientists, athletes, nurses, agricultural workers and others. All foreign workers must obtain permission to work legally in the United States. Each employment category for admission has different requirements, conditions and authorized periods of stay. It is important that you adhere to the terms of your application or petition for admission and visa. Any violation can result in removal or denial of re-entry into the United States.

Temporary (Nonimmigrant) Worker

A temporary worker is an individual seeking to enter the United States temporarily for a specific purpose. Nonimmigrants enter the United States for a temporary period of time, and once in the United States, are restricted to the activity or reason for which their nonimmigrant visa was issued.

Permanent (Immigrant) Worker

A permanent worker is an individual who is authorized to live and work permanently in the United States.

Students and Exchange Visitors

Students and exchange visitors may, under certain circumstances, be allowed to work in the United States. They must obtain permission from an authorized official at their school. The authorized official is known as a Designed School Official (DSO) for students and the Responsible Officer (RO) for exchange visitors.

Information for Employers & Employees

Employers must verify that an individual whom they plan to employ or continue to employ in the United States is authorized to accept employment in the United States. Individuals, such as those who have been admitted as permanent residents, granted asylum or refugee status, or admitted in work-related nonimmigrant classifications, may have employment authorization as a direct result of their immigration status. Other aliens may need to apply individually for employment authorization.

Temporary Visitors For Business

To visit the United States for business purposes you will need to obtain a visa as a temporary visitor for business (B-1 visa), unless you qualify for admission without a visa under the Visa Waiver Program.
