The purpose of this article is to broadly analyse the Joseonjok (Korean Chinese) enclave in Southwest Seoul under citizenship perspective. To do this it focus on the enclave’s geographical and historical background, population of Joseonjok, the citizenship status of Joseonjok since coming to Korea, the changes of citizenship status of Joseonjok in Korea, residence period, family structure, employer-employee relationship between Joseonjok entrepreneurs and workers, and so on. The results of the study are summarized as follows. The Joseonjok enclave constituted with the Joseonjok who under the citizenship status of Korean nationality, permanent residency, overseas Korean, foreign Korean worker. The primary purpose of citizenship policy which authorized to Joseonjok is effective economic contribution to the Korea’s development (or globalization). But paradoxically, the citizenship policy for Joseonjok also provide the conditions of formation of Josoenjok’s socioeconomic relationship so-called “enclave labor market(or Joseonjok enclave service economy)”. So, if we analyse the Joseonjok individuals’ socioeconomic activity together with their citizenship status, then, enclave as a case, not only can be explained by the dual labor market framework, but also can explain a part of the state-citizen (society) relationship of Korea.
