The "Outstanding Professors and Researchers" immigrant visa category was added to the first preference (EB-1) classification via the Immigration and Nationality Act of 1990 because Congress recognized that such employees provide direct contributions to the United States and U.S. workers could not meet legitimate employment needs. As such, this category is exempt from the labor certification process with the U.S. Department of Labor in which the market is tested by conducting advertising / recruitment efforts to determine whether qualified U.S. workers are available. When a Professor or Researcher qualifies, the employer must petition U.S. Citizenship and Immigration Services (USCIS) to be classified as an Outstanding Professor or Outstanding Researcher. UC International Services will not assist international employees with an outstanding petition. However, instructions on the process are given as a courtesy below.
