Wong’s research focuses on the politics of immigration, citizenship, and migrant illegality. As these issues have far-reaching implications, his work also explores the links between immigration, race and ethnicity, and the politics of identity. He is the creator of the CIR 2013 Blog, which predicts support and opposition to comprehensive immigration reform among all 535 current members of Congress, and he is the lead researcher on one of the first nationwide surveys of undocumented youth. He also recently completed a book manuscript, which analyzes the immigration control policies of 25 Western immigrant-receiving democracies, and is beginning another book on the politics of comprehensive immigration reform in the U.S., among other projects. Wong’s research has been used by policymakers both in the U.S. and in Mexico, as well as by organizations that serve immigrant communities.
