Temporary employment 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 temporary employment visa.
See our Temporary Employment Visa Categories on usvisas.state.gov to determine which visa category might be appropriate for your purpose of travel to the United States.
