So to be clear, you have dropped the documents at the consulate directly instead of shipping them? And also you have dropped/sent documents almost after 75days after submitting your application? If yes, may i know what made you take a gap of 2 and half months?
I think the timeline says that they just completed the DS 160 online on aug 5 but send the actual docs on nov 15 and it only took 8 (nov 23) days to get the status to reflect "Approved" online from the day they dropped them
