Perceptions of Threat, American National Identity, and Americans’ Attitudes Toward Documented and Undocumented Immigrants

In this paper, we explore how the effects of perceived immigrant threat, American national identity, and attitudes toward immigration-dominated racial/ethnic groups on perceptions of immigrant contributions differ for documented and undocumented immigrants. We contend that different levels of perceived risk associated with undocumented and documented immigrants activate the effects of immigrant threat and American identity in different ways. We consider the varying effects of general perceptions of immigrant threat, and we also differentiate the effects of American pride (i.e., positive sentiments about being an American) and American exclusion (i.e., negative sentiments associated with criteria needed to be considered an American). We use data from the 2016 to 2017 Voter Study Group surveys, which includes a survey experiment with respondents randomly assigned to documented and undocumented immigrant treatments. We find strong negative effects of immigrant threat perceptions on Americans support for both immigrant groups, with observed effects significantly stronger for undocumented immigrants. Further, while American exclusion has strong negative effects on attitudes for both immigrant groups, American pride depresses support only for undocumented immigrants. We also find that evaluations of Hispanics have effects on perceptions of contributions for documented and undocumented immigrants, though the effect of Asian evaluations is limited to documented immigrants.
