This Policy Memorandum (PM) provides guidance regarding the analysis that U.S. Citizenship and Immigration Service (USCIS) officers who adjudicate these petitions should use when evaluating evidence submitted in support of Form I-140, Immigrant Petition for Alien Worker, filed for:
Aliens of Extraordinary Ability under section 203(b)(1)(A) of the Immigration and Nationality Act (INA);
Outstanding Professors or Researchers under section 203(b)(1)(B) INA; and
Aliens of Exceptional Ability under section 203(b)(2) INA.
The purpose of this PM is to ensure that USCIS processes Form I-140 petitions filed under these employment-based immigrant classifications with a consistent standard.
