The current study examined 5 to 11-year-old European American children's (N = 90) attitudes regarding immigrants, immigration policy, and what it means to be an American. The majority of children in the sample (from a predominantly European American community) held strong American identities and had distinct ideas about what it means to be an American (namely, one must love America, live by its rules, and be White). Children were in favor of legal immigration as a policy, and although they believed in allowing illegal immigrants to stay if employed, many younger children believed they should go to jail. Many children in the sample were aware of Americans' anti-immigration sentiments, largely attributing it to ethnic/cultural discrimination. Finally, children held negative attitudes about immigrants, particularly Mexican immigrants. These negative attitudes were most evident among children who held a strong, prototypical national in-group identity. In contrast, children did not hold differential attitudes about White and Black Americans.
