USA
The United States is often regarded as the definitive "immigrant nation". After more than two hundred years of significant inflows, immigration to the US is characterised by its diversity. Each year large numbers of people from different socio-economic, educational and ethnic backgrounds are drawn to the country. Immigration is now both a symbol of the very essence of the US and a controversial political issue. Security has played an increasingly important role in the debate since the terrorist attacks of 11th September 2001, as has the controversy surrounding the unauthorised immigrant population.
