While considering comprehensive immigration reform, Congress called on UC Irvine sociology professor Rubén Rumbaut, a leading scholar on assimilation of immigrants and their children. He testified Wednesday, May 16, before the House Judiciary Committee’s Subcommittee on Immigration, Citizenship, Refugees, Border Security, and International Law at a special hearing, “Becoming Americans – U.S. Immigrant Integration,” in Washington, D.C. Rumbaut is the author of the award-winning Legacies: The Story of the Immigrant Second Generation, and is currently leading a major study about social mobility of immigrants in Los Angeles.
