The 18-foot-high wall separating Nogales, Arizona, from Nogales, Mexico, looms as a symbol of physical and political division. In spite of its presence, thousands of people go between ambos Nogales (both Nogales) daily, many of them visitors like the students from U of M instructor Marina Aleixo’s class, Borderland, Education Policy, and the Immigrant Student Experience. Each spring, she leads a week-long trip to Arizona. “Students have very strong reactions walking along the wall. Some are silent, some cry, others pray,” Aleixo says. “For many, it’s a tipping point, when they begin to understand immigration as a human rights issue rather than a political issue.”
