From the Middle East Times --
KUWAIT CITY -- A senior US human rights official Wednesday criticized laws in the oil-rich Gulf states that restrict migrant workers under a system that some campaigners say is akin to slave labor.
Mark Lagon, director of the Office to Monitor and Combat Trafficking in Persons, said during a visit to Kuwait that the so-called sponsorship laws restrict the choice of migrant workers and their control over their own lives.
... He pointed in particular to the sponsorship laws that he said "confine the choice and the control of their lives over migrant workers."
The system, a set of regulations that limits workers' movements and puts them at the mercy of their employers, is in place in all six Gulf Cooperation Council (GCC) states but is decried by rights bodies as akin to slavery.
This would be exactly the system of labour that was used to build the US Embassy in Baghdad.
