Essey - surely it has to be prioritized by case number not form submission date ? Ie you should get an interview before a 600 number for example.(as long as forms have been processed)
I think our forms have finally been processed too as we got the below email in reply to an enquiry rather than the one saying they are being processed.
"Your forms have been received and pending further embassy review for the continuation of your visa processing. KCC is currently scheduling visa numbers for your region for the month of November. Please refer to the visa bulletin at
www.travel.state.gov to locate the current numbers being processed. This bulletin is updated after the 15th day of each month."
