Long story short; my fiancé had her interview earlier this month (Dec 3) and the officer said she passed the interview, but she would still need to submit one of the missing forms*. My fiancé got the new form and went back to the OFC (same-day) to submit it. They sent us an email at the same time to say it would delivered to the embassy within 1 business day (Dec 4).
On USVisaScheduling website, it says 'Delivered to Post' for Passport Status and on the CEAC website it says 'REFUSED', which was last updated on Dec 10. I am freaking out because I know usually refusals mean either you start over or you get an attorney, but it also mentions that during administrative processing it will say 'REFUSED'.
Everyone I've seen on 'Administrative Processing' said they received a formal email/letter telling them about the missing documentation, but we never received that other than the verbal comment from the consulate officer.
*The missing form was a National Bureau of Investigation (NBI) Clearance. We originally brought the police clearance (white form), but they requested it be the blue form. Additionally, there is nothing on the clearance, so that shouldn't be a reason for a refusal.
