García researches state and local immigration-orientated laws in the United States and Spain. Her work investigates how unauthorized immigrant actors experience the application of restrictive and accommodating policies on the ground. Her dissertation research demonstrates how the legal contexts of immigrants’ receiving communities intersect with civic incorporation in one of the first comparative studies of the empirical outcomes of local immigration ordinances. García’s areas of expertise include international migration, law and society, race and ethnicity, Latino/a sociology, and political sociology. Her research has been published in Ethnic and Racial Studies and the Journal of Ethnic and Migration Studies, along with book chapters with Harvard University Press and Lynne Reinner Publishers. García has briefed Congressional staffers on the outcomes of state and local immigration measures and has commented on this issue in Spanish and English-language media.
