I really do not want to ruin your hopes but I had the same situation like you, first time i sent my file in may 2017 and forgot to sign the forms as sponsor, they sent it back in July 2017. I signed forms and sent it back in July 2017 and this time forms and documents checklist was updated already, so they sent it back in September. 3rd time i sent it on September 22 2017, this time everything was Ok and they gave AOR 1 on October 31 2017. I am still waiting for the update, so that i can say that they have considered me as a September Applicant. But again, We can never expect any pattern from NDVO. Just want to tell you that be prepared for at least 10 or 11 month from December.
