This may be a "nation of immigrants," but unauthorized immigrants are no longer welcomed as “huddled masses yearning to be free. When their US-born children live in fear that their parents will be deported, they are collateral damage from harsh new policies. The title of a new book says it all: Forgotten Citizens: Deportation, Children and the Making of American Exiles and Orphans. It's about the people getting left out of the long, loud debate about immigration, the children of undocumented immigrants. The author is Luis Zayas, dean of the School of Social Work at the University of Texas, Austin.
