The purpose of this study is to analyze the residential segregation of foreign immigrants from developed and developing countries, respectively. This paper finds that the level of residential segregation of foreign immigrants from developing countries is higher than those from developed countries in terms of the dissimilarity index, the isolation index, the delta index, the proportion of the centralization index, and the Moran's I index. However, the residential distribution of foreign immigrants from developing countries is not similar with the spatial distribution of unskilled manufacturing jobs. In addition, the high level of isolation index means that their residential pattern can increase the possibility of their social exclusion.
