Compared to the Gulag labor camps, the involuntary settlements had the appearance of "normal" settlements: people lived in families, and there was slightly more freedom of movement; however, that was only permitted within a small specified area. All settlers were overseen by the NKVD; once a month a person had to register at a local law enforcement office at a selsoviet in rural areas or at a militsiya department in urban settlements. As second-class citizens, deported peoples designated as "special settlers" were prohibited from holding a variety of jobs, returning to their region of origin, attending prestigious schools, and even joining the cosmonaut program. After the special settlement system was officially abolished in the 1950s, most deported indigenous peoples were allowed to return to their homelands, except for the Crimean Tatars and Meskhetian Turks, who were denied the right of return in the Khrushchev and Brezhnev era and largely remained in areas they were deported to because of the residence permit system.
