Whilst immigration policy is a highly controversial topic in the West, states continue to receive people who settle, whether as asylum-seekers or refugees, or as family members of existing migrants or labour migrants. Many who move violate the immigration rules either in entering a country or staying beyond the time allowed. The problems illegality entails for migrants shape much of the law and society scholarship in this area and this volume brings together the key articles which shape current thinking. The main topics covered include illegality, mercy and the language of deservingness; transnationality; family and identity; refugees and asylum-seekers.
