House of Green Cards

Abstract

This study contributes to the labor market inequality and organizations literature by investigating the role that government agents play in shaping the employment of immigrants. Using unique data on applications for immigrant permanent labor certification evaluated by U.S. Department of Labor agents, we assess to what extent immigrants of select citizenship groups experience disparities in the labor certification process—one critical stage of the work authorization system leading to the granting of most employment-based green cards. Despite current U.S. laws that forbid discrimination on the basis of nationality, we find that labor certification approvals differ significantly depending on immigrants’ foreign citizenship, even after controlling for key factors. Additionally, because of the U.S. government’s unique process of auditing applications, we are in a rare position to empirically distinguish between statistical and preference-based accounts of labor market discrimination in the labor certification process. In support of the statistical account, we find that certification approvals are equally likely for immigrant workers from the vast majority of citizenship groups when agents review audited applications with detailed employment information. This article concludes by discussing the implications of our results for addressing disparities in the employment of foreign nationals.
