 However, the definition of "ordinary residency" excludes (amongst other groups) those who lived in the territory as foreign domestic helpers; this effectively denied foreign workers the rights of permanent residents (including the right to vote), even if they had lived in Hong Kong for many years.Since 1997, section 2(4) of the Immigration Ordinance has stated that "a person shall not be treated as ordinarily resident in Hong Kong while employed as a domestic helper who is from outside Hong Kong".In 2011, the issue of foreign workers applying for Hong Kong residency was debated; since one million families live under the poverty line in the territory, some political parties argued that Hong Kong has insufficient welfare funding to support 300,000 foreign workers if they can apply for public housing and social-welfare benefits.
