A: Entries means the number of times that a person is permitted to enter into a country within the validity of a visa. Visas become invalid when the applicants have fully used the Entries permitted. Entries once permitted can not be added or changed. Should applicants need more Entries to China, they have to apply for another visa. A visa becomes invalid when an applicant fails to use it before the date of Enter before even if Entries on it are still unused. Applicants should check the validity of Entries permitted before they depart for China.
