An expatriate (in abbreviated form, expat) is a person temporarily or permanently residing in a country and culture other than that of the person 's upbringing or legal residence. The word comes from the Latin ex (out of) and patria (country, fatherland).
During the latter half of the 20th century expatriation was dominated by professionals sent by their employers to foreign subsidiaries or headquarters. Starting at the end of the 20th century globalization created a global market for skilled professionals and leveled the income of skilled professionals relative to cost of living while the income differences of the unskilled remained large. Cost of intercontinental travel had become sufficiently low, such that employers not finding the skill in a local market could effectively turn to recruitment on a global scale.
BACKGROUND
Any major organization operating internationally could rely entirely on staff recruited locally. Most do so for the majority of positions. However, most companies also employ expatriates, those who work outside their country of origin, for a variety of reasons. In some cases, these workers fill skill gaps when local staff is unavailable; in other cases, they may be sent to train local staff or to install companywide systems in areas like IT and finance. Some may be sent on developmental assignments to gain skills and experience at an early stage of their careers. Increasingly, part of the motivation is to ensure that the company’s future top-management cadre has some international experience.
Whatever the reason for using expatriates, this relatively small group of people takes a disproportionate amount of HR time. In setting pay for key local staff, employers must ensure that they are competitive with the local job market and that they offer challenging jobs within a country with the prospect of advancement within that country. However, this approach is insufficient for expatriates, whom employers must view by reference
