Foreign labour service providers are not allowed to charge any service fees or ask for deposits or financial guarantees from the workers they have signed labour contracts with, the circular said.
Foreign labour service corporations should not allow other companies or individuals to recruit workers on their behalf or allow their employees to work for businesses related to gambling or pornography, it said.
And they should also buy personal accident insurance for their workers, except when foreign employers have promised to cover insurance fees, the circular said.
Foreign labour service companies should send administrative staff to accompany teams of overseas workers consisting of more than 100 people, according to the regulations.
