paragraph_text: Ellis Island, in Upper New York Bay, was the gateway for over 12 million immigrants to the United States as the nation's busiest immigrant inspection station for over sixty years from 1892 until 1954. The island was greatly expanded with land reclamation between 1892 and 1934. Before that, the much smaller original island was the site of Fort Gibson and later a naval magazine. The island was made part of the Statue of Liberty National Monument in 1965, and has hosted a museum of immigration since 1990.

paragraph_text: Guam is served by the Antonio B. Won Pat International Airport, which is a hub for United Airlines. The island is outside the United States customs zone so Guam is responsible for establishing and operating its own customs and quarantine agency and jurisdiction. Therefore, the U.S. Customs and Border Protection only carries immigration (but not customs) functions. Since Guam is under federal immigration jurisdiction, passengers arriving directly from the United States skip immigration and proceed directly to Guam Customs and Quarantine.

paragraph_text: Originally populated by the indigenous Taíno people, the island was claimed in 1493 by Christopher Columbus for the Crown of Castile during his second voyage. Later it endured invasion attempts from the French, Dutch, and British. Four centuries of Spanish colonial government transformed the island's ethnic, cultural and physical landscapes primarily with waves of African slaves, and Canarian, and Andalusian settlers. In the Spanish imperial imagination, Puerto Rico played a secondary, but strategic role when compared to wealthier colonies like Peru and the mainland parts of New Spain. Spain's distant administrative control continued up to the end of the 19th century, helping to produce a distinctive creole Hispanic culture and language that combined elements from the Native Americans, Africans, and Iberians. In 1898, following the Spanish -- American War, the United States acquired Puerto Rico along with other Spanish colonies under the terms of the Treaty of Paris.

paragraph_text: Berkeley became the first city in the United States to pass a sanctuary resolution on November 8, 1971. Additional local governments in certain cities in the United States began designating themselves as sanctuary cities during the 1980s. Some have questioned the accuracy of the term ``sanctuary city ''as used in the US. The policy was first initiated in 1979 in Los Angeles, to prevent the Los Angeles Police Department (LAPD) from inquiring about the immigration status of arrestees. Many Californian cities have adopted`` sanctuary'' ordinances banning city employees and public safety personnel from asking people about their immigration status.

The deposition of Fulgencio Batista's dictatorship and the ascension of Fidel Castro's government in 1959 increased Cuban immigration to the United States, hence there are some one million Cubans in the United States, most settled in southern and central Florida, while other Cubans live in the Northeastern United States; most are fluent in Spanish. In the city of Miami today Spanish is the first language mostly due to Cuban immigration.

paragraph_text: 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.

paragraph_text: The history of Chinese Americans or the history of ethnic Chinese in the United States relates to the three major waves of Chinese immigration to the United States with the first beginning in the 19th century. Chinese immigrants in the 19th century worked as laborers, particularly on the transcontinental railroad, such as the Central Pacific Railroad. They also worked as laborers in the mining industry, and suffered racial discrimination at every level of society. While industrial employers were eager to get this new and cheap labor, the ordinary white public was stirred to anger by the presence of this ``yellow peril ''. Despite the provisions for equal treatment of Chinese immigrants in the 1868 Burlingame Treaty, political and labor organizations rallied against the immigration of what they regarded as a degraded race and`` cheap Chinese labor''. Newspapers condemned the policies of employers, and even church leaders denounced the entrance of these aliens into what was regarded as a land for whites only. So hostile was the opposition that in 1882 the United States Congress eventually passed the Chinese Exclusion Act, which prohibited immigration from China for the next ten years. This law was then extended by the Geary Act in 1892. The Chinese Exclusion Act was the only U.S. law ever to prevent immigration and naturalization on the basis of race. These laws not only prevented new immigration but also brought additional suffering as they prevented the reunion of the families of thousands of Chinese men already living in the United States (that is, men who had left China without their wives and children); anti-miscegenation laws in many states prohibited the Chinese men from marrying white women.

paragraph_text: In 1997 the Pier 21 facility was designated a National Historic Site of Canada on the recommendation of the Historic Sites and Monuments Board of Canada because of the facility's major role in 20th century immigration in Canada and because it is the last surviving seaport immigration facility in Canada. The Pier 21 Society opened an interpretive centre in part of the former immigration facility in 1999. The society became the Canadian Museum of Immigration at Pier 21 in 2010, and occupied an expanded portion of the former immigration facility. The Nova Scotia College of Art and Design's seaport campus took over Pier 21's former medical, detention and accommodation wing in 2011. The Garrison brewing company leased a large portion of the immigration annex building in May 2006. A variety of retail shops as well as artists' and architects' studios and cultural organizations occupy the remainder of the immigration annex.

paragraph_text: On August 10, 1815, the Royal Decree of Grace was issued, allowing foreigners to enter Puerto Rico (including French refugees from Hispaniola), and opening the port to trade with nations other than Spain. This was the beginning of agriculture-based economic growth, with sugar, tobacco, and coffee being the main products. The Decree also gave free land to anyone who swore their loyalty to the Spanish Crown and their allegiance to the Roman Catholic Church. Thousands of families from all regions of Spain (particularly Asturias, Catalonia, Majorca and Galicia), Germany, Corsica, Ireland, France, Portugal, the Canary Islands and other locations, escaping from harsh economic times in Europe and lured by the offer of free land, soon immigrated to Puerto Rico. However, these small gains in autonomy and rights were short lived. After the fall of Napoleon, absolute power returned to Spain, which revoked the Cádiz Constitution and reinstated Puerto Rico to its former condition as a colony, subject to the unrestricted power of the Spanish monarch.
