The history of immigration to the United States details the movement of people to the United States starting with the first European settlements from around 1600. Beginning around this time, British and other Europeans settled primarily on the east coast. Later Africans were imported as slaves. The United States experienced successive waves of immigration, particularly from Europe. Immigrants sometimes paid the cost of transoceanic transportation by becoming indentured servants after their arrival in the New World. Later, immigration rules became more restrictive; the ending of numerical restrictions occurred in 1965. Recently, cheap air travel has increased immigration from Asia and Latin America.
