ying use of these terms for different groups of foreigners can be seen as implying nuances about wealth, intended length of stay, perceived motives for moving, nationality, and even race. This has caused controversy, with some commentators asserting that the traditional use of the word "expat" has had racist connotations. An older usage of the word expatriate referred to an exile. Alternatively, when used as a verbal noun, expatriation can mean the act of someone renouncing allegiance to their native country, as in the preamble to the United States Expatriation Act of 1868 which states: 'the right of expatriation is a natural and inherent right of all people, indispensable to the enjoyment of the rights of life, liberty and the pursuit of happiness'. Some neologisms have been coined, including: dispatriate, an expatriate who intentionally distances themselves from their nation of origin; flexpatriate, an employee who often travels internationally for business (see "Business expatriates" below); inpatriate, an employee sent from a foreign subsidiary to work in the country where a company has its headquarters; rex-pat, a repeat expatriate, often someone who has chosen to return to a foreign country after completing a work assignment; sexpat, an expatriate with the goal of short or long term sexual relations
