I have been COMPLETE since mid-July, so today I called Admissions and inquired about my application. Apparently my application is currently being reviewed by a subcommittee, but all my status page says is COMPLETE. I had read on this thread that the "subcommittee status" is usually a bad thing, so I asked her if the adcom had reservations about my application. She then told me that all applicants are reviewed by the subcommittee before being granted an interview. This really confused me because I thought that this status meant a low priority score. Am I misinterpreting subcommittee evaluation for "subcommittee status"? Anybody have any thoughts?
This actually happened to me too. I kept getting complete status changes so I called to ask about my app. The lady told me I was being reviewed by a subcommittee, which I interpreted to be exactly what you said (not so good). My status still says complete though, which is confusing. I'm not getting my hopes up though, since they may just be trying to be nice about a poor status. That is a little confusing though...
This exact same thing happened to me. I got two different complete statuses separated by a few weeks from VCU. When I got the second one, I thought that it may have been a mistake, so I called the admissions office. The lady there told me that "my application had gone to sub-committee". I interpreted this to mean that my status should have been the one that mentions the sub-committee, (which on SDN has determined to be a not-so-desirable status), and figured my chances at VCU were fairly limited.
Over the next week or so, I received at least two more "complete" statuses via email notification. I was wondering what in the world was going on, but decided to give it some time. A few days later, I received and interview invite (today).
My best guess is that everyone goes to an interview sub-committee before they're actually offered an interview spot. This must be why the admissions office told myself, and you YPDCC, that our apps were at sub-committee.
They probably have a whole different meeting or committee for the folks that they give the actual "sub-committee" status update. Maybe for those who received a lower-priority score upon the initial review.
Just a guess, but it makes sense to me? Who knows though..
Regardless, good luck!!!

Edit: Oh, I forgot, also amongst that second bunch of "complete" statuses, I eventually received the "may" status. Then a few days later the ii came.
