I have been tracking my applications on the USCIS website, daily. Out of curiosity, I checked a few number before/after mine, and noticed there was a bit of a pattern. I would like to share this with you guys, so you can tell me what you think!

As I mentioned, my service center is Vermont (EAC), and my receipt numbers end in 68 & 68
(One for the 821-D, and one for the 1-765.)

The below receipt numbers are 821D & 1765 related, this is what I found:

52,53- approved 10/31
54,55-approved 11/1
56,57-approved 11/2
58,59-
60,61-
62,63-
64,65-approved 11/8
66,67-
