Your expiration date is same as mine, and I sent my packet in the beginning of July.
Now I am scheduled for my fingerprint on this coming Tuesday.
I doubt that you can request your renewal application to be expedited (You can do that for AP)
And to be honest, with the amount of time people on this forum is waiting, I feel that the processing time is actually a lot slower than what the previous renewal had been. With all that being said, I suggest you prepare & send your packet right away.
