On the other hand, human rights organizations have criticized Kuwait for the human rights abuses toward foreign nationals. Foreign nationals account for 70% of Kuwait's total population. The kafala system leaves foreign nationals prone to exploitation. Administrative deportation is very common in Kuwait for minor offenses, including minor traffic violations. Kuwait is one of the world's worst offenders in human trafficking. Hundreds of thousands of foreign nationals are subjected to numerous human rights abuses including involuntary servitude. They are subjected to physical and sexual abuse, non-payment of wages, poor work conditions, threats, confinement to the home, and withholding of passports to restrict their freedom of movement. Since the start of the COVID-19 pandemic vaccination rollout, Kuwait has been regularly accused of implementing an xenophobic vaccine policy toward foreign nationals.
