If a servant stays in HK long enough, like 10-15 years. Earned enough money to support her own living. Or even having kid growing up in HK. Should we consider citizen for her?
According to immigration law of HK, not just about length of stay in HK. We should consider the applicant for citizenship can support his/her own living in HK(financially). ans did he/she got permanent living place in HK.
So I would say only a very small portion on servants meet these requirements.
The no of 150,000 is like a joke.
