This research examined how immigration consultancy firms (ICFs) affect immigrants’ settlement process and, why potential immigrants rely on ICFs to deal their immigration application. Data for this research were collected in Calgary through semi-structured interviews and analysis of secondary data. This research explored two main findings. Firstly, this research revealed that ICFs partially influenced potential immigrants’ selection of landing cities in Canada, with the selective information they provided to potential immigrants. Furthermore, ICFs influence secondary migration from other Canadian cities to Calgary. Secondly, ICFs broke the chain of migration networks changing the model of immigration from one that builds and expands social networks to one that breaks and replaces them. This research also analyzed the situation and political background surrounding the rise of ICFs. This exploration demonstrated that private immigration companies gradually replaces the role of social networks in immigration and their negative results such as fraud and secondary migration.
