The following discussion concerns the emergence of and interrelations between the concepts of expatriation, migration, and “othering” in present Buenos Aires. The arguments rest on my fieldwork in Argentina, as well as other studies from around the world. The research on expatriates is usually based in Asia or the UAE, and the region of Latin America is still quite understudied in this respect. Buenos Aires as the “city offoreigners” represents an anthropologically interesting fieldsite. Next to the mostly quantitative research on expatriates, anthropology can give us a better understanding of their practices and experiences. Furthermore, it challenges our ideas of these concepts weuse to describe different groups of people (e. g. expatriate, immigrant), and allows us tounderstand how they are socially constructed. Hence, my study offers a new view on expatriation in a broader context of post-colonialism and current trends in globalization.The city's historical context must be considered as well in order to understand the complexities of terms such as foreigner or immigrant.
