Change in US Address - Please help

[newuser_8_06]

My mother has a visa appnt in November. They got the appointment in April . We have to move from our current address the one mentioned on DS-156 to a new place end of this month. What should we do about the change of address. My parents physically delivered the form to VFS. They did not do it online.
Is there any way we can update the form.

They can update it at the time of interview.
