You might be right. I just can't find any valid explanation as to why some December applications are opened before they even finish opening October applications.Then how do you explain someone from October receiving AOR now?
The process should be pretty simple: just sort the applications by the day you received them and each agent can take a new application from the earliest unopened application whenever they finish verifying the previous one.
I can understand that there might be delays after the initial opening and verification depending on your case and the center processing them but for the AOR it should be pretty straightforward.
Anyway, that's how it is and we have to deal with it.
