TY - RPRT AU - Sparber, Chad TI - Weighting the H-1B Lottery: Implications for Worker and Diversity and Employment Concentration PY - 2025/Dec/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 18333 UR - https://www.iza.org/index.php/publications/dp18333 AB - The H-1B program allows firms in the United States to temporarily hire foreign workers in specialty occupations.
