Hey guys,
I sent my amcas app in on 8/24 and I was verified on 9/12. My verified app was transmitted to all my schools by 9/23. I called AMCAS about the way they verify apps and they say they do it in order they are received. They say delays usually occur if transcripts are lost, not received, and if there are significant errors on the submitted app. You might want to contact them if you aren't verified in the next few days. Good luck!
