Foreign migrant workers

The glossary of statistical terms, published by the Organisation for Economic Co-operation and Development (OECD), suggests that migrants consist of four categories:

long-term immigrants (or emigrants);
short-term immigrants (or emigrants);
residents returning after (or leaving for) a period working abroad, i.e. short-term emigrants returning (or leaving); and
nomads.

It defines foreign migrant workers as: ‘foreigners admitted by the receiving State for the specific purpose of exercising an economic activity remunerated from within the receiving country. Their length of stay is usually restricted as is the type of employment they can hold.’
