expat

An expatriate (often shortened to expat) is a person who resides outside their country of citizenship.
The term often refers to a professional, skilled worker, or student from an affluent country. However, it may also refer to retirees, artists and other individuals who have chosen to live outside their native country.
The International Organization for Migration of the United Nations defines the term as 'a person who voluntarily renounces his or her nationality'. Historically, it also referred to exiles.
