The start of DS-260 processing is according to the submission date, and it does have a sense. Otherwise someone with low case number could jam the process if it doesn't submit DS-260.Thanks you so much for you reply really thanks a lot once again …!!! As you said i also agree with you that they will have less time for processing then why still they are not sending if they are processing ds 260 according the CN we would get for now but they are processing according the ds260 submitted order because higher than our case number has got 2nl its being 15 days since our CN became current……!!!
How long DS-260 processing will take depends on many factors, like the complexity of the case, if DS-260 is unlocked with some major change if applicants are added later, etc...
