A valid passport and visa are required to enter and exit China. The visa must have been obtained from a Chinese embassy or consulate before traveling to China. A U.S. citizen arriving without a valid passport and the appropriate Chinese visa will not be permitted to enter China and will be subject to a fine and immediate deportation at the traveler's expense. Chinese authorities have recently tightened their visa issuance policy, in some cases requiring personal interviews of U.S. citizens. Although a bilateral United States-China agreement provides for issuance of multiple-entry visas with validity of up to one year for tourists and business visitors, Chinese consulates often limit visas to only one entry. Visas are not required of U.S. citizens who hold air tickets to a final destination other than China, have booked seats on international airliners flying directly through China, and will stay in a transit city for less than 24 hours without leaving the airport.
Persons transiting China on the way to and from Mongolia or North Korea or who plan to re-enter China from the Hong Kong or Macau Special Administrative Regions should be sure to obtain visas allowing more than one entry.
Please note that non-U.S. passport holders are responsible for obtaining the required documentation applicable for their entry.
