Sorry to hear. We had our K1 interview at Mumbai exactly 1 year ago tomorrow (Jan 5, 2012) and we were denied citing the same - they think we are already married - we're not! We're awaiting USCIS decision now. Best of luck to you both!
Congrats on getting interview date. good luck with everything.
They haven't even send our packet 3 yet. When I contacted them, they told me that the application hasn't even been entered into computer yet. Told me to be patient.
