Complete at Stanford on 11/21. Submitted app 11/09, and Stanford put in the LSAC request the very same day! My dean's certification was sent in like a week ahead of my app and my stuff was all ready to go at LSAC when I submitted, so I think that both of those things helped speed it up.
Haven't heard ANYTHING from Columbia yet, although they did request my report right away... I guess they're busy with ED apps right now since I'm sure my dean's certification got there before my app, just like Stanford.
