As countries such as the United States have put increasing funding and importance towards immigration detention, private prisons have entered the fold. The first private immigration detention center in the US was also established in the mid-1980s, and many other countries in the global north followed suit. For example, the use of Guantanamo Bay as an offshore detention center served as a precedent for Australia to establish offshore immigrant detention centers in Nauru and Papua New Guinea. Overall, using immigrant detention centers, border patrols, and other control measures is an established practice around the world in order to maintain political and social borders created by dominant social groups.
