How to cancel Hong Kong immigration

If you don't move to Hong Kong and travel between China and Hong Kong, you can only apply to visit relatives and travel to and from Hong Kong. Visiting relatives can stay in Hong Kong for 90 days at a time.

If you want to apply for the right of abode, because you are husband and wife, you can apply for the right of abode as long as you move to Hong Kong and live in Hong Kong continuously for seven years. So you want to stay in Hong Kong, but the idea that you can go back to the mainland to see your parents at any time is not feasible. Either you stay in the mainland and apply for visiting relatives when you go to Hong Kong, or you can apply for a one-way permit immediately and get it to move to Hong Kong. If you move to Hong Kong, your parents can still apply for moving to Hong Kong as long as they are over 60 years old.
