Throughout America's nearly 250-year history, the nation has both embraced immigrants and made them the targets of hate crimes, exclusion laws, and discrimination. Refugees, asylum seekers, migrant workers, and others from around the world have crossed U.S. borders in search of work, food, shelter, and religious freedom. This nonfiction social studies title for young adults examines the challenges immigrants in the United States face, from language barriers to health care access, and the benefits immigration provides to the economy and society. Includes sidebars, a glossary, a timeline, and profiles of Zoom founder Eric Yuan and electrical engineer Katya Echazarreta.
