The Department of Homeland Security (DHS) is proposing to amend its regulations governing employment-based immigrant petitions in the first, second, and third preference classifications. Petitions for these classifications are filed by employers, or in certain cases by noncitizens on their own behalf, to bring talent and skills to the United States. The proposed rule would, if finalized, codify current policy guidance and implement administrative decisions regarding successorship-in-interest and ability to pay; update provisions governing extraordinary ability and outstanding professors and researchers; modernize outdated provisions for individuals of extraordinary ability and outstanding professors and researchers; clarify evidentiary requirements for first preference classifications, second preference national interest waiver (NIW) classifications, and physicians of national and international renown; implement reforms to ensure the integrity of the I-140 program; and correct errors and omissions. Many of the proposed revisions derive from public engagement. Specifically, USCIS held a public engagement to solicit suggestions for regulatory and policy reform for employment-based immigrant classifications on December 21, 2021. USCIS also published a broad request for public input in the Federal Register, 86 FR 20398 (Apr. 19, 2021), which resulted in suggestions for employment-based immigration classifications.
