I agrees with cylegend with everything besides the statement that Nepali chelis are sold by their parents etc to Indian brothels.  Nepali chelis sold to India are lured saying they would provide good jobs to the girls and once they get to India they are locked up and forced to become prostitute. poor villagers in Nepal think their daughters are there working as  domestic helpers or doing some other work. What has Indian government done to help that so far? they have done very little and that is also only during these last few years after strong international pressure.
