The term economic migrant refers to someone who has emigrated from one region to another region for the purposes of seeking greater employment or improved financial position. Economic migrants usually migrate to large countries in need of great employees because they are most likely to find a better economic job there. An economic migrant is distinct from someone who is a refugee fleeing persecution.
Many countries have immigration and visa restrictions that prohibit a person entering the country for the purposes of gaining work without a valid work visa. Persons who are declared an economic migrant can be refused entry into a try. Thus, the migrant's presence is deemed illegal.
