1. The IOM definition covers inter alia those persons who have entered a transit or host country lawfully but have stayed for a longer period than authorised or subsequently taken up unauthorised employment.
2. 2. The term 'irregular' is preferable to 'illegal' migrant because the latter carries a criminal connotation, entering a country in an irregular manner, or staying with an irregular status, is not a criminal offence but an infraction of administrative regulations. Apart from this, juridically and ethically, an act can be legal or illegal but a person cannot. Thus more and more the term 'migrant in an irregular situation' or 'migrant with irregular status' is preferred.
3. The European Commission has used the term 'third-country national found to be illegally present' or 'illegally resident/staying third-country national' in legislation.
4. The Council of Europe differentiates between illegal migration and irregular migrant. Referring to Resolution 1509 (2006) of the Council of Europe Parliamentary Assembly , ‘illegal’ is preferred when referring to a status or process, whereas 'irregular' is preferred
