Do I need to give up my mainland passport and hukou to apply for permanent residence in Hong Kong?

To apply for permanent residence in Hong Kong, you must give up your mainland passport and account.

Because if you want to get a HKSAR passport, you must give up your mainland residence and China passport. No matter how you move to Hong Kong, you will be issued with a Hong Kong identity card and become a Hong Kong resident. However, to apply for permanent resident status in Hong Kong, you need to live in Hong Kong for more than 7 years.

Living continuously for more than 7 years only means that you have the right to apply for permanent resident status, but it doesn't mean that you have to apply.

Right of abode in Hong Kong:

China citizens who were born in Hong Kong or have ordinarily resided in Hong Kong for more than seven years before or after the establishment of the Hong Kong Special Administrative Region and their children born outside Hong Kong;

Other people who have ordinarily lived in Hong Kong for more than seven consecutive years before or after the establishment of the Hong Kong Special Administrative Region and have taken Hong Kong as their permanent residence, and their children under the age of 21 born in Hong Kong before or after the establishment of the Hong Kong Special Administrative Region.

Therefore, children born in Hong Kong can become mainland citizens by taking Hong Kong permanent residents.
