Hong Kong visa is not required for tourists from more than 160 countries. A stay ranging from 7 to 180 days is granted according to nationality. People from those Hong Kong visa free countries, however, need to get a HK visa if they intend to work, study, establish or join in a business there or if their tour is beyond the granted visa-free stay length. Also, other countries' citizens have to get a HK visa before leaving for HK as it's almost impossible to get it on arrival. Although Hong Kong is a part of China, as a Special Administrative Region (SAR), it has its own entry regulations. This means the normal Chinese visa does not work for Hong Kong and vice versa.
Generally, Hong Kong is very open to foreigners who simply want to visit as a tourist to conduct business activities for an overseas business such as visiting clients and prospects, providing training, or attending trade fairs. Overall, the rules are essentially the same as under the British administration that preceded the SAR's return to Chinese control.
