Rescheduling B2 visa to a later date beyond the travel date mentioned in DS160

[nikhil14b]

Hi,

The b2 visa is scheduled for 18th Jan and in the DS 160 the travel dates are mentioned as 20th Jan - 15th Feb
OF is done. Now i want to reschedule the interview to 1st Feb. But this will conflict with the DS160 mentioned travel dates. So do i need to modify the DS 160 form as well for the later travel dates?

Also, will i need to do OFC again? And fee?

Please help me understand the procedure. Thanks.
