After getting an entrepreneur visa, you can apply for an identity card. In Hong Kong, the identity card is a requirement for all persons over the age of 11 years. The same case applies to other visa holders. The identity card is very important because it contains a microchip with all your information that can be used to access public resources such as libraries.
After applying for the identity card, it takes about 30 days to process. Besides, you should notify the authorities within 14 days if it gets lost. After staying for 7 years with non-resident identity card, you can apply for a permanent one.
