So you received your AOR on Oct 21st, but they may have entered your file in the system on Sept 20th meaning someone actually worked on the file on that day after receiving it on the 16th. After that they will forward the file to the next dept. who issue the AOR. Since AOR are coming through an automated system, it took time for you to receive it and that is why there is date difference. Consider Sept 20th as your processing date even though it won't make any difference as they are way behind right now.No necessarily “it means what it says” my friend
If you read what I said, my app was delivered on Sept 16th not Sept 20th and ecas says they received it to their office Sept 16th. However I got my AOR on Oct 21st. Does that mean they started to process my application on Sept 20th?
