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.
根据美中双方签署的延长签证有效期的协议，自2016年11月起，凡持有10 年 B1，B2 或 B1/B2签证的中华人民共和国护照持有人需要每两年或在获取新护照时（无论哪种情况先发生），通过网站更新他们签证申请上的个人资料及其他信息。这个机制我们称之为EVUS –签证更新电子系统。
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. For further information, please visit www.cbp.gov/EVUS.
