Hong Kong’s High Court has ruled that a domestic helper, maid,  from the Philippines should be allowed to apply for permanent residency in the city. The ruling follows a landmark judicial review and could lead to more than 100,000 other foreign maids winning rights to residency. The government has said that it will appeal against the ruling.
I think granting them the residency will lead to a threat to the limitation of resources such as health care, employment, education and housing. Hong Kong is already a very packed place with approximately seven millions people. Allowing the population to grow by granting them residency would probably lead to much more strain on the economy.
