Donald Trump’s recent proposals to deport all undocumented immigrants and build a wall between the U.S. and Mexico are only two of the latest controversial ideas on immigration. Historically, one side of the debate blames immigration for society’s troubles and calls for restricting immigrant numbers, while the other contends that the U.S. is a nation of immigrants and condemns anti-immigrant rhetoric as racist and xenophobic. This volume explores these views, as well as recent policy discussions related to the DREAM Act, counter-terrorism, the policing of borders, and education.
