Anxiety: Difference and Danger,
FROM ITS EARLIEST DAYS, the United States has been anation defined by immigration. Beginning with voyages to theNew World by European explorers hundreds of years ago, successive waves of newcomers have shaped and defined the culture that would become America. Defined as the movement of people from one nation to another, immigrants differ from visitors or tourists because they establish permanent residences in the destination country. Immigration occurs for a wide variety of reasons. Some people move for employment or a higher standard of living, others immigrate to escape oppression or political persecution, and some immigrate to join family members. Attitudes toward immigration vary greatly from nation to nation. Some countries willingly permit citizens to leave or enter, while others perceive immigration as problematic. For these reasons, immigration often is regulated by laws, border protections, or even military action.
