Immigration (derived from Latin: migratio) is the act of foreigners passing or coming into a country for the purpose of permanent residence. Immigration is made for many reasons, including economic, political, family re-unification, natural disaster, poverty or the wish to change one's surroundings voluntarily.

The International Organization for Migration (IOM) stated there are more than 200-million migrants around the world today. Europe hosted the largest number of immigrants, with 70 million people in 2005. North America, with over 45 million immigrants, is second, followed by Asia, which hosts nearly 25 million. Most of today's migrant workers come from Asia.

The United Nations found that in 2005, there were nearly 191 million international migrants worldwide, about 3 percent of the world population. This represented a rise of 26 million since 1990. Sixty percent of these immigrants were now in developed countries, an increase on 1990. Those in less developed countries stagnated, mainly because of a fall in refugees. Contrast that to the average rate of globalization (the proportion of cross-border trade in all trade), which exceeds 20 percent. The numbers of people living outside their country of birth is expected to rise in the future.

Joseph Robinette "Joe" Biden, Jr. (pronunciation: /ˈdʒoʊsɨf rɒbɨˈnɛt ˈbaɪdən/; born November 20, 1942) is the 47th and current Vice President of the United States, serving under President Barack Obama. A Democrat, he was a United States Senator from Delaware from January 3, 1973 until his resignation on January 15, 2009, following his election to the Vice Presidency.

Biden was born in Scranton, Pennsylvania and lived there for ten years before moving to Delaware. He became an attorney in 1969, and was elected to a county council in 1970. Biden was first elected to the Senate in 1972 and became the sixth-youngest senator in U.S. history. He was re-elected to the Senate six times, was the fourth most senior senator at the time of his resignation, and is the 15th-longest serving Senator in history. Biden was a long-time member and former chairman of the Foreign Relations Committee. His strong advocacy helped bring about U.S. military assistance and intervention during the Bosnian War. He opposed the Gulf War in 1991. He voted in favor of the Iraq War Resolution in 2002, but later proposed resolutions to alter U.S. strategy there. He has also served as chairman of the Senate Judiciary Committee, dealing with issues related to drug policy, crime prevention, and civil liberties, and led creation of the Violent Crime Control and Law Enforcement Act and Violence Against Women Act. He chaired the Judiciary Committee during the contentious U.S. Supreme Court nominations of Robert Bork and Clarence Thomas.

Nigel Paul Farage ( /ˈfærɑːʒ/, FARR-ahzh; born 3 April 1964, Farnborough, Kent), is a British politician and is the Leader of the UK Independence Party (UKIP), a position he also held from September 2006 to November 2009. He is a Member of the European Parliament for South East England and co-chairs the Eurosceptic Europe of Freedom and Democracy group.

Farage is a founding member of the UKIP, having left the Conservative Party in 1992 after they signed the Maastricht Treaty. Having unsuccessfully campaigned in European and Westminster parliamentary elections for UKIP since 1994, he gained a seat as an MEP for South East England in the 1999 European Parliament Election — the first year the regional list system was used — and was re-elected in 2004 and 2009. Farage describes himself as a libertarian and rejects the notion that he is a conservative.

In September 2006, Farage became the UKIP Leader and led the party through the 2009 European Parliament Election in which it received the second highest share of the popular vote, defeating Labour and the Liberal Democrats with over two million votes. However he stepped down in November 2009 to concentrate on contesting the Speaker John Bercow's seat of Buckingham in the 2010 general election.

Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known as one of four co-founders of the social networking site Facebook, of which he is chairman and chief executive.

Zuckerberg was born and raised in a Jewish household in New York state. While still in middle school in his early teens, he took up writing software programs as a hobby, beginning with BASIC, with help from his father. His father then hired a tutor to help his son develop his programming skills further. Zuckerberg's enjoyment in writing programs led him to developing computer games, writing a music player, and setting up a primitive home network he called "ZuckNet." His private tutor calls him a "prodigy." In high school he excelled in classic literature and science, while becoming proficient in four other languages. He was also captain of the school's fencing team.

He later enrolled in Harvard, majoring in computer science and sociology. In his sophomore year he wrote a program called Facemash as a "fun" project, letting students on the college's network vote on other students' photo attractiveness. It was shut down within days, but would become a template for his writing Facebook, a program he launched from his dormitory room. With the help of friends, including roommate Dustin Moskovitz, Facebook went national on other campuses, and they moved to Palo Alto, California. By 2010, the site had an estimated 500 million users worldwide. Zuckerberg and Facebook have since been involved in various legal disputes initiated by others who have claimed a share of the company's profits due to their help in setting it up. Zuckerberg is the largest individual shareholder with 28.4 percent of the common stock and controls 56.9 percent of the voting power. As of 2012^[update], his personal wealth was estimated at more than $19.1 billion, making him one of the world's youngest billionaires. Zuckerberg is one of the 30 richest people on Earth.

Grover Glenn Norquist (born October 19, 1956) is an American lobbyist, conservative activist, and founder and president of Americans for Tax Reform. He is a member of the Council on Foreign Relations. He is best known as the promoter of the "Taxpayer Protection Pledge", which was signed by 95% of all Republican Congressmen and all but one of the 2012 Republican presidential candidates, to oppose increases in marginal income tax rates for individuals and businesses, as well as net reductions or eliminations of deductions and credits without a matching reduced tax rate.

Norquist grew up in Weston, Massachusetts. He is the son of Carol (née Lutz) and Warren Elliott Norquist, a vice president of Polaroid Corporation. Norquist became involved with politics at an early age and in his early teenage years he volunteered for the 1968 Nixon campaign, assisting with get out the vote efforts. He graduated from Weston High School and enrolled at Harvard University in 1974, where he obtained both a B.A. and an M.B.A.. While in college, Norquist was an editor at the Harvard Crimson and helped to publish the libertarian-leaning Harvard Chronicle. Norquist has said: "When I became 21, I decided that nobody learned anything about politics after the age of 21." He attended the Leadership Institute in Arlington, Virginia, an organization that teaches conservative Americans how to influence public policy through activism and leadership.
