On November 29, 2016, all Chinese individuals carrying maximum validity (10-year) B1/B2, B1, and B2 visas in passports issued by the People’s Republic of China must have a valid EVUS enrollment in order to travel to the United States. Travelers who are subject to EVUS requirements but do not have valid enrollments will not be able to obtain a boarding pass or enter through a land port of entry.
An EVUS enrollment is valid for two years or until the traveler obtains a new passport or “B” visa, whichever comes first. Other classes of visa (F, J, H, etc.) do not have to enroll in EVUS.
Please visit Youku or QQ to view a video demonstration of EVUS.
