In introduction to the special issue we argue that immigration is a phenomenon that shifts space and time.it is an ageless human strategy to improve life and could be defined as a natural behavior of human being. So there have been immigrants and immigration to what is now known as Britain for more than thousand years .They helped to create the foundation of the country we know today. People that go there are often known as invaders, immigrants, refugees, sojourners (people that stay temporarily) and more recently asylum seekers and illegal migrants. Some settled permanently, some stay for just short while and then move on, as for as others return to their roots. So "IMMIGRATION " is a term which can be defined as a movement of people inward the countries or across international borders. Indeed, this movement particularly, across international borders that people invented, has become an important policy issue for the governments all over the world because it affects the lives of people in many areas. In the other term "IMMIGRATION " derived from Latin: migratio is an act of people entering and settling in the country or region to which they are not native. It is made for many reason including economic political, family re-unification, national disaster, poverty or the wish to change one's surrounding voluntarily. Despite, difficulties, problems finding in this area immigration continued widely in Britain because of it appeal as a place of security and opportunity after the World War II,and by that time Britain became a country of immigration following the large scale of immigration from its former and current colonies. And at the end of this second world war in 1945, Britain was quickly recognized that the reconstruction of British economy required a large influx of immigrants labour.The Royal commission on population reported in 1949 that immigrants of good stock would be welcomed without reserve, and potential newcomers from the Caribbean and elsewhere soon became aware of pressing needs of labor market in the united kingdom.
