我是美国公民， 我帮助父母办理的移民签证， 我父亲收到了NVC的email 说要月底去广州面签， 但是因为广州疫情， 而且我母亲的签证也没下来， 请问如何才能改时间呢？ 可以以疫情为借口来延期吗？ 怎么延期？ 问了广州的领馆说要email， 但就没有消息了， 打电话给NVC说一定要领馆来处理才行， 这样怎么办， 急！ 谢谢
-You need to contact NVC and the US Consulate, and explain your reasons for wanting to reschedule. You must provide your case number or application number and let them know of a time that is convenient for you so they can try to get you that appointment. The NVC and the US Consulate, however, will schedule the appointments at the next available timeslot if the one you are requesting is not available.
