Legal Passing offers a nuanced look at how the lives of undocumented Mexicans living in the U.S. are constantly shaped by federal, state, and local immigration measures. Angela S. García compares restrictive and accommodating immigration laws in various cities and states and argues that restrictive laws paradoxically drive greater integration and incorporation into the community. By taking on characteristics associated with mainstream Americans, undocumented Mexicans mask the stigma of illegality and present themselves (through dress, speech, and other habits) as “legal” to the point where it becomes habitual and internalized, contributing to their acculturation. Rather than fully obstructing the path to adaptation, restrictive subnational laws unwittingly motivate it. Combining social theory on race and immigration as well as place and law, Legal Passing uncovers the everyday failures and long-term human consequences of anti-immigrant legislation.
