Fueled by the politics of xenophobia and national security, the United States immigration enforcement system has expanded and strengthened in recent decades, resulting in more abuses of Mexican migrants by United States officials during apprehension, detention, and deportation. We find that the geography of United States enforcement operations and the social characteristics of the Mexican consular districts in which migrants report these abuses determine when and where the Mexican state assists Mexican nationals who are targets of abuse. Our findings illustrate the limits of sending-state engagement in safeguarding the rights of its diaspora in an age of migration control.

在仇外心理和国家安全的推动下，近几十年来，美国移民执法系统得到了扩大和加强，导致美国官员在逮捕，拘留和驱逐出境中对墨西哥移民的虐待行为增多。我们发现，美国执法行动的地理位置以及移民报告有这些虐待行为的墨西哥领事区的社会特征，决定了墨西哥国家何时何地协助遭受虐待的墨西哥国民。我们的研究结果表明，在移徙控制时代，派遣国参与维护其侨民权利的局限性。
