mintshel, I have the same question ... when did your status change to "under review"? My status changed to "under review" on October 26th but I have not heard anything yet... finger crossed waiting for an interview. Good luck with your interview!
My status went under review on Oct 8th. Like another alumni told me, tt will take about 5 weeks for Adcom to review. But I apply from Taiwan, circumstances may be different.
