USCIS Policy Memorandum PM-602-0005.1 (December 22, 2010) updated the USCIS Adjudicator's Field Manual, and provided USCIS adjudicators with guidance on adjudicating Form I-140, Immigrant Petition for Alien Worker, for employment-based first preference petitions (EB-1) filed for Aliens of Extraordinary Ability under INA section 203(b)(1)(A), Outstanding Professors or Researchers under INA section 203(b)(1)(B), and employment-based second preference petitions (EB-2) filed for Aliens of Exceptional Ability under INA section 203(b)(2).

The guidance incorporated standards identified in the 9th Circuit Kazarian decision, and finalized and superseded an interim Policy Memorandum that USCIS had issued on August 18, 2010. NAFSA had commented on the interim guidance, focusing its remarks on the E12 outstanding professor and researcher category. The final memo incorporates several of NAFSA's comments, and provides greater detail on standards for evaluating evidence submitted in support of I-140 petitions filed under the Outstanding Professors or Researchers category.
