I have a piece of paper in front of me which was given to me by the friendly chap from the Immigration Department when they confirmed my PR status a few weeks ago. He called my attention to three sections of the information:
Category of persons who acquired permanent resident status by virtue of being
(1)A person not of Chinese nationality who has entered Hong Kong with a valid travel document has ordinarily resident in Hong Kong for a continuous period of not less than 7 years and has taken Hong Kong as his place of permanent residence before or after the establishment of the HKSAR.Circumstances under which the person will lose the status of a permanent resident
If the person has been absent from Hong Kong for a continuous period of not less than 36 months since he ceased to have ordinarily resided in Hong Kong.Pretty clear from this that Right to Land is what you get when you lose PR status - so by definition, you cannot be both PR and have Right to Land.Right to land
A person who ceases to have the status of a permanent resident of the HKSAR will automatically acquire the right to land in Hong Kong in accordance with the law. He will be able to enter Hong Kong freely to live, study or work without any restrictions. A person my ascertain whether he has lost the status of a permanent resident of the HKSAR by applying for verification of eligibility for permanent identity card with the Right of Abode Section of the Immigration Department for assessment of whether he has lost the permanent resident status and has the right to land in the HKSAR.
