Changing start date and end date after of approval after booking interview

[visadude]

Hello!

I booked my L1 individual visa appointment today and in the cgifederal website, in petitioner information I gave the wrong start and end date for my I-797 approval notice. I’m unable to modify the dates online. How can I get this changed? I called customer care and they mentioned it can be done during biometrics appointment date. Anyone else had experience with this? Any help is much appreciated.

thanks.

You can submit a new DS160 & talk to customer care to update your DS160 number with the new one & you can use that during your interview.
