EVUS登记不是签证。它不符合律或法规的要求以替代美国签证，当根据美国法律要求签证时。计划前往美国访问的旅客出行必须持有有效的B1，B2或B1 / B2级访客签证。身为中华人民共和国公民/国民的旅客仅持有有效的十年B1，B2或B1 / B2级签证，必须在EVUS上申请登记，并且在行前持有签证。如果您已在EVUS登记并抵达机场，该旅客将可以前往美国。其他任何非B1，B2或B1 / B2具有十年有效期类型的签证，不需要申请EVUS登记。
What is the difference between EVUS and a Visa?
An EVUS is not a Visa. It does not meet the legal or regulatory requirements to serve as a U.S. Visa when a Visa is required under U.S. law. Travelers who plan to travel to the United States as visitors must possess a valid visitor Visa, class B1, B2 or B1/B2. Travelers who are People's Republic of China citizens / Nationals with B1, B2, or B1/B2 10 year valid Visas only, are required to enroll with EVUS and must have a Visa prior to travel. If you are enrolled with EVUS and arrive at the airport the traveler will be able to travel to the United States. Any other class of Visa that is not B1, B2, or B1/B2 with a 10 year validity will not be required to apply for an EVUS.
