Mainland Chinese does not automatically qualify to apply for an Investment or Employment Visa to Hong Kong. Mainland Chinese is required first to reside overseas (other than Hong Kong, Macau & Mainland China) for at least 12 months immediately before submission of an Investment or Employment Visa application. Otherwise the investment or employment visa application will not be accepted.
For those Mainland Chinese graduates who have been studying for degree level courses in any universities in Hong Kong, they can also apply for an Employment Visa directly to Hong Kong Immigration Department provided they have secured positions offered by an established company immediately after their graduation. They have to fulfill the rest of the requirements for an employment visa application.
This is designed for those professional people who have been residing in Mainland China. As a normal employment visa application for Mainland Chinese requires them to reside overseas for at least 12 months, so this scheme is similar to a normal employment visa application but for those Mainland Chinese who has not fulfilled the 12 months overseas residency requirement.
