In the eye's of the HKSAR rule of law, prostitution is illegal.. We can naturally assume that, excluding the stereotypical part time moon lighters that already typify WanChai's more sordid underbelly, then, anybody else that has been internationally procured for the purpose of sex work, would be infact an illegal worker, plying an illegal activity... Umm mah ! lol
Curious that you support prostitution, which is a criminal offence in HK, but you are the first to pounce on a cheeky British subject, the moment they make inquiries on this forum, with view to working here for 6 months as an English tutor on a tourist visa, albeit, illegally, but with more innocent intent, than professional whoring.
Quiet an interesting moral construct, that you have...
