<span>The history of immigration to the United States is a continuing story of peoples from more populated continents, particularly Europe and also Africa and Asia, crossing oceans to the new land. Historians do not treat the first indigenous settlers as immigrants. Starting around 1600 British and other Europeans settled primarily on the east coast. Later Africans were brought as slaves. During the nation's history, the growing country experienced successive waves of immigration which rose and fell over time, particularly from Western Europe, with the cost of transoceanic transportation sometimes paid by travelers becoming indentured servants after their arrival in the New World. At other times, immigration rules became more restrictive. With the ending of numerical restrictions in 1965 and the advent of cheap air travel immigration has increased from Asia and Latin America, much of the latter "illegal." Attitudes toward immigrants have cycled back and forth between favorable and hostile since the 1790s. </span>
