It can be confirmed that Hong Kong permanent residency and mainland household registration can coexist. But why have we all heard the saying that you can only choose one of the two?

When applying for Hong Kong permanent residency, the immigration officer will ask the applicant to sign a declaration to cancel their mainland household registration. However, this declaration does not affect the progress of the permanent residency application, and it is not required when collecting the permanent residency ID card; 80% of friends applying for Hong Kong identity do so to allow their children to enjoy the preferential mainland university admission policies, such as the low score of 400 points for overseas Chinese students to enter mainland key universities, and the admission policy for Hong Kong DSE students, where most of the 129 985/211 universities can be admitted with a score of 3322. However, both exams require the "Home Return Permit" to register. During the application process, one document must be provided, which is the "Cancellation of Mainland Household Registration Certificate"; hence the saying that applying for Hong Kong permanent residency requires canceling the mainland household registration.

For business people who need to travel or be on business trips for a long time, if they need to transit through Hong Kong to reach their destination, continuing to use the Hong Kong and Macau travel permit (with a 7-day stay limit) can significantly delay their travel plans, and sometimes they might accidentally end up on a blacklist. If they obtain a "Home Return Permit," they will not be subject to stay limits.

In short, Hong Kong permanent residency and mainland household registration can coexist.
