Visa Information

General Visa Information for China

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 2 months 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.

Necessary materials to apply for Chinese Visa

  • Original signed passport – must be at least 1 yr valid with 2-3 clear visa pages;
  • One recent, 2 inch full-faced and bareheaded passport photo (the daily life photo, photo copy or digital photo printed on the ordinary paper shall not be accepted) Click here for photo requirements;
