To work in the United States temporarily as a lawful nonimmigrant, temporary workers must qualify for the available visa category based on the planned employment purpose.
Temporary worker visas are for persons who want to enter the United States for employment lasting a fixed period of time, and are not considered permanent or indefinite. Each of these visas requires the prospective employer to first file a petition with U.S. Citizenship and Immigration Services (USCIS). An approved petition is required to apply for a work visa.
Refer to Temporary Employment Visas for more information.
