签证是新签的,EVUS也是第一次注册,紧接着就收到这个信,登入查看显示已登记,要8月底才去
美国,这个是什么情况,求高人指点!ATTENTION! The enrollment submitted on 2017-07-06 03:18:00.387 via EVUS will expire within the next 30 days. It is not possible to extend or renew a current EVUS enrollment. You will need to enroll for a new EVUS. Please reenroll at https://www.evus.gov if travel to the United States is intended in the near future. If there are 30 or more days left on the old enrollment you will receive a warning message during the enrollment and be asked if you wish to proceed.
