According to the website of the U.S. Customs and Border Protection, after 2011,all China citizens with valid visas of 10 B 1 or B2 must complete the registration of the electronic visa renewal system (EVUS) before they can get permission to enter the United States. All applicants are registered for two years. If the passenger's visa or passport expires, the information registered by EVUS will be invalid. Then the visa holder must log in to EVUS again to update his personal information before going to the United States.
(1) Applicants who hold B 1/B2 or B 1 or B2 visas issued before 201in 2006 and valid for 10 years can only apply for visas after the regulations take effect.
(2) Applicants who have obtained B/KOOC-0//B2 or B/KOOC-0//B2 visas valid for 10 years since June 20/KOOC-0/6 must register before their first trip to the United States.
Extended data:
EVUS must be registered in English. Every time you register on EVUS, you need to provide your name, date of birth, emergency contact, passport information, personal and employment information, and you need to answer questions related to travel qualifications. Friends, relatives, professional tourists or other third parties can also submit the registration of EVUS instead of passengers.
Registering in EVUS requires a small fee to keep the system running. The cost information will be provided before the EVUS system is started.
