To enter China you will require a passport valid for at least 6 months beyond the date of entry with at least 2 blank pages. A visa will need to be organized prior to your arrival. For this you will require a completed application form with one passport photo (two for US citizens) and your passport. Allow 5-10 working days for processing. It is your responsibility to ensure all visa and entry requirements are met prior to arrival in China.
Tibet is a part of China and as such the normal China tourist visa applies for Tibet. In addition to the China tourist visa, permits are required for visits to each region of Tibet. Note that permits are arranged by tour company for client travel to Tibet and thus do not need to be arranged by the client or the agent.
Visitors from most countries, including citizens of the European Union, Australia, New Zealand, the USA, Canada and Japan, can enter Hong Kong (a Special Administrative Region of China) without a visa for periods of 90 days to six months, depending on nationality. Check with any Chinese embassy or consulate for the latest status.
