Can I apply for a household registration book when I immigrate to Hong Kong?

1. The application for permanent residence in Hong Kong (permanent identity card) has nothing to do with the cancellation of the mainland account. If you move to Hong Kong and work, live and study in Hong Kong after holding a temporary residence permit in Hong Kong, it will not affect your mainland account, so there is naturally no need to cancel it.

2. Even if you meet the conditions of normal residence for seven years, you don't need to cancel your mainland account when you apply for permanent residence in Hong Kong. Applying for a HKSAR passport is not directly related to the cancellation of your mainland account.

It is very important if you want to apply for home visit permit.

The state's management of dual household registration in the two places is mainly to limit the process of handling home visit permits. If you apply for a home visit permit, you need to cancel your mainland account first. If you do not apply for a home visit permit, but only apply for a Hong Kong permanent identity card, you do not need to cancel your mainland account.
