According to the U.S. State Department, expatriate workers from nations throughout Asia and parts of Africa voluntarily migrate to Qatar as low-skilled laborers or domestic servants, but some subsequently face conditions indicative of involuntary servitude. Some of the more common labor rights violations include beatings, withholding of payment, charging workers for benefits for which the employer is responsible, restrictions on freedom of movement (such as the confiscation of passports, travel documents, or exit permits), arbitrary detention, threats of legal action, and sexual assault. Many migrant workers arriving for work in Qatar have paid exorbitant fees to recruiters in their home countries.
