"Two-Step Approach" Form I-140 Petitions Evaluation

USCIS has issued a Policy Memorandum for "Two-Step Approach" Form I-140 Petitions Evaluation. This Policy Memorandum provides guidance regarding the analysis that Immigration Service Officers must use in adjudicating Form I-140, Immigrant Petition for Alien Worker, filed for: EB1 - Extraordinary Ability petitions, EB1 - Outstanding Professor or Researcher petitions, and Aliens of Exceptional Ability, including EB2 NIW petitions. Once USCIS determines that the petitioner has provided satisfactory evidence for the requisite number of prongs, the second phase of review requires the adjudicator to weigh the evidence against the required high level of expertise for the visa category. It is in the second phase of the review where the evidence can be evaluated to see if, cumulatively, it proves by a preponderance of the evidence that the applicant or beneficiary is at the very top of his or her field of endeavor. For your case, you need to work on the criterion of academic contribution in your field. A good way is to run a new report of your paper's citation number. You also need to prove that you are one of that small percentage who has risen to the top of the field of endeavor and, and you have sustained national or international acclaim. http://www.greencardapply.com/question/question14/EB1A-Two-Step-Approach_0401.htm
