The containment of immigrants along the US/Mexico border illuminates the complex spatial implications associated with the securitization of migration enforcement. The production of marginalized, carceral national spaces has particular consequences for the people who inhabit them, as processes of spatial illegality shape their daily lives. Our analyses draw on five years of ethnographic study in the Rio Grande Valley of Texas. Here, we focus on the experiences of sixty‐one undocumented youth, including recipients of Deferred Action for Childhood Arrivals, to explore how the spatial violence created by checkpoints and everyday policing practices lead to experiences of confinement and accelerate processes of social exclusion. Spillover effects occur as all inhabitants must pass through inspection points and demonstrate proof of identity and legal residency; this contributes to the reformulation of citizenship. To this, our article adds insight into how social membership is experienced at the checkpoints so that “citizenship” and “authorization” become conflated. Early childhood and youth experiences of freely crossing spaces with school programs yet living with uncertain and precarious status contribute to persistent fear, instability, and confusion under a multilayered immigration policy regime.

限制青年移民的地区：美国/墨西哥边境沿线的检查站和固定装置

美国/墨西哥边境沿线的移民收容措施说明了与移民执法证券化相关的复杂空间含义。边缘化，国家化的民族空间的产生对居住在那里的人们产生了特殊的后果，因为空间违法行为改变了他们的日常生活。我们的分析借鉴了得克萨斯州里奥格兰德河谷的五年人种志研究。在这里，我们重点关注六十一名无证件青年的经历，包括推迟到达儿童行动组织的接受者，以探讨检查站和日常警务实践造成的空间暴力如何导致拘禁和加速社会排斥的过程。当所有居民必须通过检查站并证明身份和合法居住权时，就会发生溢出效应；这有助于重新制定公民身份。为此，我们的文章为如何在检查站体验社会成员身份提供了见识，从而使“公民身份”和“授权”混为一谈。在多层移民政策制度下，幼儿期和青少年期的经历使他们可以自由地穿越学校课程，但生活状况不确定且不稳定，这会导致持续的恐惧，不稳定和混乱。
