What does EVUS have to do with the 10-year visa?

In November 2014, the Governments of the United States and China entered into an arrangement on a reciprocal basis to issue 10-year visitor and business travel visas (B1/B2, B1, and B2). That same arrangement recognized that travelers would be required periodically to complete an online form updating the information they used to apply for the visa. EVUS was developed to allow travelers to provide the most current information – including name, passport number, address, and employment – to immigration officials before traveling to the United States.
