F Visas: How to Respond to a RFE on an OPT Extension

Hi,

I started working as a full time employee on CPT from August 2015. I graduated in Dec 2015 and my CPT expired on Dec 31st 2015.

While filling my OPT application form in OCT 2015, I filled in Jan 4th 2016 as my OPT start date since I thought Jan 1st, 2nd and 3rd are holidays so Jan 4th can be my OPT start date. But then it dint come to my mind that I would still be an employee of my company during those three days.

Now when I got my RFE on OPT extension, they asked me for my start and end dates of my employment history, I am confused if Aug 2015 would be my start date or Jan 4th 2016? I never had any termination in between.

Please advice?

Thanks
Rani
