In accordance with the agreement signed between the United States and China to extend visa validity, beginning in November 2016, Chinese citizens with 10-year B1, B2 or B1/B2 visas in Peoples’ Republic of China passports will be required to update their biographical and other information from their visa application via a website every two years, or upon getting a new passport, whichever occurs first. This mechanism will be called EVUS - Electronic Visa Update System.
You do not need to take any action until the EVUS online update system becomes available in November 2016. The Department of Homeland Security, Customs and Border Protection (CBP) will keep visa holders informed of new information throughout the year.
