In recent decades, Canada and other democracies have experienced a significant rise in migrant settlement. This has sparked much interest among scholars and policy makers in the forces that encourage or impede the political incorporation of newcomers. In this research note, we consider a factor that has received relatively little scrutiny, the impact of immigrants’ attention to native-country politics on willingness to participate in residential-country elections and affiliate with a political party in that country. We examine this through an original survey of Americans in Canada conducted during the 2020 US election cycle. A randomized experiment demonstrates that directing the attention of American emigrants to US campaigns can lower interest in Canadian elections and weaken attachments to a Canadian political party, particularly for those who are less integrated into Canadian society. These findings point to a potential tension between political engagement as an emigrant versus as an immigrant.
