The kafala system, present in a number of other Muslim countries, governs the conditions and processes for employment of foreigners. Under this system, all non-Saudis present in the country for employment purposes must have a sponsor, which is usually arranged months in advance.[29] Unlike countries which recognize the Universal Declaration of Human Rights (which declares in part "Everyone has the right to leave any country, including his own")[30] Saudi Arabia requires foreign workers to have their sponsor's permission to enter and leave the country, and denies exit to those with work disputes pending in court. Sponsors generally confiscate passports while workers are in the country; sometimes employers also hold passports of workers' family members.[29]
