This work is aimed at professionals who work in the fields of welfare and education and who increasingly require knowledge of immigration law and politics. It shows how restrictions are historically a product of racism and argues that there can not be "fair" controls. The link between immigration status and entitlement to welfare and social provision means that immigration and asylum law directly impinges on major areas of life. The text begins by covering the main issues. The new Nationality, Immigration and Asylum Act is explained - including material on how education entitlement is now to be linked to immigration status. Part One of the work provides a political background to immigration controls and shows why there cannot be non-racist controls. Part Two covers the historical background. Part Three examines internal welfare controls. Part Four looks at the international aspects of controls and how a global fortress is being erected against migrants, immigrants and refugees. Part Five gives examples of resistance to immigration controls.
