An expatriate (often shortened to expat) is a person who resides outside their country of citizenship.[1]
The term often refers to a professional, skilled worker, or student from an affluent country.[2] However, it may also refer to retirees, artists and other individuals who have chosen to live outside their native country.[citation needed]
The International Organization for Migration of the United Nations defines the term as 'a person who voluntarily renounces his or her nationality'.[3] Historically, it also referred to exiles.[4]
The UAE is the country with the highest percentage of expatriates in the world after the Vatican City, with expatriates in the United Arab Emirates representing 88% of the population.[5][6]
