Wait a minute. If my current salary is 2m+, then I can apply for a work visa to stay in HK for another 6 years and, during those 6 years, work for whoever I want without informing immigration? What if I get this visa and then change to a part-time job and start earning much less than 2m, do I still keep this right to work here and the right to apply for PR when the time comes? What about my dependants?
