You need to appl a visa for HK. You can submit your application to Chinese embassy at least one month before your trip. You know, the embassy will send your application to HK Immigration Department. It takes four to six weeks for them to decide whether you will be granted or not.
Required documents are: copy of passport information page, application form, two recent passport photos,original certificate of your company (business license), introduction letter from your employer (signed and stamped), invitation letter from your sponsor in HK, your financial statement, previous records to HK (if any).
