Hi everyone,
I am trying to understand the breakdown of my USCIS receipt number <Deleted>
Based on what I have read, the standard breakdown is:
MSC = National Benefits Center
<Deleted>
907 = Computer workday (??)
<Deleted>
My confusion is around the "907" — FY2022 only has approximately 260 working days (Oct 1, 2021 to Sep 30, 2022), so 907 clearly cannot represent a workday in the traditional sense.
Does anyone know what the "907" actually represents for MSC cases specifically? Is NBC/lockbox using a different numbering system than other service centers?
For context: my I-485 was filed on September 21, 2022 (EB-2 India, priority date September 9, 2013). The case is now current as of April 2026 and I am actively waiting for final adjudication.
Thanks in advance!
