Illegality and Irregularity

Migrants whose residence is not state authorized, or who are breaking their conditions of entry have a wide range of descriptors – illegal, undocumented, irregular, clandestine, non-compliant, unauthorized, trafficked, sans papières etc. Claims to knowledge and analysis tended to be heavily politicised, and the terminology used often indicates a particular position. Yet it is far from clear what exactly is meant by “illegal immigration”? Is it a problem to be solved, or a phenomenon characterising nation states in the global economy? Is it an end state, a category, or a process?
