Dual identities are defined as immigrants' identification with their ethnic ingroup as well as the national community in their country of residence. Dual identities have been argued to increase protest, because they make immigrants feel entitled to advocate for their disadvantaged ethnic group as part of a larger national community. In a study of Latino immigrants to the United States, however, we found that dual identities no longer predict protest when immigrants learn that other members of the national community have passed laws or enacted policies that would exclude immigrants or restrict their rights, through deportation and detention. Further, we found that immigrants who identify with those fighting to change such anti-immigrant policies support protest regardless of the level of their dual identity and regardless of policy salience. We argue that these results point to the importance of dual identity recognition for research on immigrant protest. Copyright © 2014 John Wiley & Sons, Ltd.
