As far I recall, I didn't get an email stating my file was complete. However, I did have several specific questions, so I called my Regional Admissions Officer at West Point to clarify and was assured everything was in.
I would say wait a few days, and if you don't hear back, call West Point, and just ask to verify that everything is in and ask if they think there is anything else you can do to make your file more competitive.
Not sure, but I might have heard somewhere that the board will not be meeting again until next semester, Jan. 10, but not 100% positive on that so if someone else knows anything else, let me know.
Hope that helps!
Good Luck!!!
