This foundational memorandum applies the Hand Formula (B < PL) to the “Substantial Prospective Benefit” requirement of the EB-1A classification. It argues that the probability (P) of the Beneficiary’s future contributions, multiplied by the gravity of the loss (L) to the U.S. economy if denied, significantly outweighs the burden (B) of granting the petition. This logic establishes a rational basis for approval, creating a compelling economic argument that the Beneficiary’s admission is not merely a benefit, but a necessity for maintaining U.S. competitiveness in their field.
