I-I29Fs don't have priority dates. Maybe you are referring to your actual receipt date?
Kitkat I understand what you’ve said. However, on the replacement receipt notice paper, the received date field is blank, priority date field is 20070407 and the notice date field is 08/03/2007. Could it be because this is a replacement receipt notice and this is the reason priority date is used? Also, it appears to be a generic replacement receipt notice because there were text on the paper that mentioned form I-130 and applications requiring biometrics.
Anyway, I just got off the phone with CSC and here are my findings: mails service are contracted out and the 20070427 date is the date stamped for my package by the mail service company that originally received my I-129F package. The 05/23/2007 date is the date that USCIS clerk entered my information into USCIS database with regards to this application. She did acknowledge that it was a bit odd that my priority date is the same date as when I dropped off the package at the post office since USPS does not provide same day delivery service between Chicago & Nebraska. Anyway, she indicated it was to my own advantage and this is the date they have in the system and it will never change. Perhaps this was an error on the part of the mail service company albeit a good error for me.
