memo: Well, they don't know the exact reason, all that I was told is that each case goes to different officers depending upon the case background and respective officers have there own queues, this is kind of weird, I sometimes think the guys at the service desk don't know what they are talking about.... my school decided to follow up with their liason at the USCIS and expect to hear something today or monday so keeping my fingers crossed, if it takes another 114 days....
Good Luck to every one who is the mercy of USCIS!!
