Hong Kong maintains a separate and independent immigration system from that of mainland China. This means that unlike mainland China, visitors from most countries can enter Hong Kong without a visa for periods of seven days to six months, depending on natioality. Check with the Chinese embassy or consulate for the latest status.

However, this also means that a seperate visa is still required to enter mainland China from Hong Kong. Detailed visa requirements are available from the Immigration Department at a Chinese embassy or consulate. Those who require visas should apply for for one at a Chinese embassy, but note that the Hong Kong vise has to be applied for seperately from the mainland Chinese one. Many nationalities are able to get a an onward visa for mainland China issued while in Hong Kong. In the foyer in the arrivals area at Hong Kong International Airport you will find a kiosk that issues them. Remember that a photograph will be required.
