Migrant sex work
Because of their illegal and vulnerable economic status, some migrant sex workers may find themselves in situations where coercion and forced sex work may be present. Under international legal definitions of human trafficking, forced and coercive forms of sex work are considered to be instances of involuntary sex trafficking. However, many scholars caution against categorizing sex workers as either completely voluntary or completely involuntary. They often argue that sex work, like other forms of labor, can span a spectrum between the two extremes, with most circumstances falling in the middle through various labor rights violations. Nevertheless, the vulnerability of migrant sex workers can make them susceptible to exploitative or coercive labor practices that can resemble or be human trafficking.
Sex trafficking in the United States
The prostitutes in illegal massage parlors may be forced to work out of apartment complexes for many hours a day. Many clients may not realize that some of the women who work in these massage sex parlors are actually forced in prostitution. The women may initially be lured into the US under false pretenses. In huge debt to their 'owners', they are forced to earn enough to eventually "buy" their freedom. In some cases women who have been sex trafficked may be forced to undergo plastic surgery or abortions. A chapter in "The Slave Next Door" (2009) reports that human trafficking and sexual enslavement are not limited to any specific location or social class. It concludes that individuals in society need to be alert to report suspicious behavior, because the psychological and physical abuse occurs which can often leave a victim unable to escape on their own.
