i just submitted my ds 160 not long ago and after i realized i made a mistake on it. i tried going back to fix it but it wouldn't let me. my questions are, 1. if i submit a new one with a new barcode/confirmation number will that be okay? 2. will the old ds 160 get deleted after submitting a new one? 3. will they have access to both forms and review both of them? i don't want any confusion at all during interview. please clear answers would be appreciated. this is for a k1 fiancé visa, no fee has been paid yet and no interview has been scheduled.
