The analysis shows that human capital accumulation and interactions with non-Hispanic white Americans are important to learning English in this migrant population. But it also suggests that membership in an MTN can inhibit the acquisition of English language proficiency. I use Mexican Migration Project data and other accumulated research to argue that being undocumented and participating in MTNs can deter migrants from assimilating into American mainstream society: a lack of legal status among many first-generation Mexican immigrants pushes them toward survival strategies that rely on MTNs %K migration-trust networks %K collective efficacy %K social capital %K undocumented immigration %K paisanos %U https://journals.sagepub.com/doi/full/10.1177/0002716219855024
