The Gulf Labour Markets and Migration (GLMM) Programme uses the two internationally accepted definitions provided by the United Nations for “international migrant:

GLMM and its institutional partners, the Gulf Research Center (GRC) and the Migration Policy Centre (MPC) at the European University Institute (EUI), are aware of the fact that the words migration (Arabic: hijra) and migrant (muhajir) are generally not used in the member states of the Gulf Cooperation Council (GCC) and that, instead, other terms are used to describe the foreign nationals who enter the GCC countries such as: those who came from outside (al-wafidun); migrant workforce (al-‘amala al-wafida); foreign workforce (al-‘amala al-ajnabiyya); non-nationals (ghayr muwatinun); expatriates (al-mughtaribun), etc.

GLMM prefers the terms “inward migration” and “outward migration” to, respectively, “immigration” and “emigration” that are commonly understood as movements of persons who intend to settle at a destination.

GLMM as a scientific, independent and non-partisan programme and its institutional partners, GRC and MPC/EUI, have no official opinion concerning the duration of stay of foreign nationals; whether they intend to settle or return to their country of origin; whether they are allowed to settle or not; whether they are de facto long-term residents or not; whether they want to become GCC citizens or not, etc. GLMM collects data – in primis, official data produced by the GCC states and by countries of origin – and documents (e.g., laws, plans, and policies) that describe population by citizenship, country of birth, duration of residence, education, occupation, etc.
