The Basic Law (BL) is the constitutional document of the Hong Kong Special Administrative Region (HKSAR). Put into effect on July 1, 1997, it enshrines within a legal document the important concept of “One Country, Two Systems.”
Q. Has there been an influx of Mainland residents coming to live in Hong Kong?
A. No. Entry into the HKSAR from other parts of China is subject to strict immigration controls in the same way it was before the reunification. Mainland residents wishing to settle in Hong Kong do so under the One-Way Permit Scheme, which has a daily quota for arrivals. (BL Article 22)
