Dear forum mates when I goggle dv2015 winners Facebook I just found one post, which says about receiving mail from kcc for his inquiry of visa appointment , his case number is 279xxx from Djibouti current on April , and kcc respond with mail notifying his appointment date, time and place before they send the 2nl , even they put the duration when he is going to receive second notification through mail. (7-10Days).
I think After being current it is possible to know the exact date of interview before receiving the second notification letter.
See the attachment mail they sent to him posted on dv2015 winners Facebook.
