Visa Application

护照.pngVisa Application


Conference participants may need a Chinese visa to enter China. Specifically, those who are not Chinese citizens, except passport holders from Singapore, Brunei, and Japan, need a Chinese visa. Participants can apply for a visa at the Chinese embassy or consulate in the region in which they live. To avoid uncertainty, participants will be advised to apply for a visa as early as possible. It is recommended that they apply for a Chinese visa at least 1 month in advance.

For most attendees, it is easier to apply for a Tourist ("L") visa; an invitation letter is NOT required for obtaining a Tourist visa.

* For more information, please contact the local Chinese Embassy in your country.
