U.S. Citizenship and Immigration Services has released updated policy guidance in the Policy Manual, aimed at providing clarity on the eligibility criteria for EB-1 immigrant visa classifications, specifically for extraordinary ability (E11) and outstanding professor or researcher (E12). The guidance outlines examples of evidence that can meet the criteria or be considered comparable, with a particular emphasis on science, technology, engineering, or mathematics (STEM) fields. This update is designed to offer a clearer understanding of the evidentiary requirements and considerations for petitioners, facilitating the submission of appropriate evidence to establish the beneficiary's eligibility. The intent is to enhance transparency and provide more explicit guidance for those navigating the EB-1 classification process. For further details, refer to the Policy Manual on the USCIS website.
