THE working committee overseeing Hong Kong's transitional matters will consider a scoring system to assess whether people want to take Hong Kong as their place of permanent residence after 1997. The proposal will be raised by Law Shuk-ching in the Preliminary Working Committee (PWC) for the Special Administrative Region Preparatory Committee's law and order sub-committee meeting on Sunday. Under the system, an applicant's intention to take Hong Kong as his permanent residence would be assessed by whether he owned property in Hong Kong, whether he had a stable job here, whether he could speak Cantonese and whether he had relatives who were already permanent residents. ''I think, for example, we can work out a plan in which the pass mark may be 60 out of a total of 100,'' he said. Another PWC member, Lee Wui-ting, said the scheme would affect dual passport holders, foreign nationals, people who had secured a full British passport through the British right of abode scheme and senior civil servants. Although the Sino-British Joint Liaison Group had yet to work out the implementation of the Chinese nationality law in Hong Kong after 1997, Mr Lee said under the Chinese law any ethnic Chinese would lose his Chinese nationality once he had a foreign nationality. Regarding the method to judge a person's desire to take Hong Kong as his place of permanent residence, Mr Lee, who is also an assistant director of the local Xinhua (New China News Agency), said the most important thing was to spell out a set of criteria. Under the Basic Law, a non-Chinese can only become a permanent resident of Hong Kong if he has lived in Hong Kong for more than seven years and has taken Hong Kong as his place of permanent residence.
