07/31/07 USC secondary submitted
08/01/07 USC secondary completed
The day I submitted is the day my LORs were received by USC (UPS tracking) as well as the day I sent electronically the app. I got recognition of my LORs and complete status a few days after. I did call the person though, she said normally it takes 4-6 weeks before they scan them into the system, so just sit tight. GL!
