I've gotten a few calls in the past week from students who thought they submitted their applications, but who haven't gotten email confirmations from us about getting into the UVa Student Information System, where status pages are found.
In these cases, I've found that students have submitted one part of the application (payment, for example), but they haven't actually submitted the Common App Basic and UVa Supplement. Be sure to check your main Common App page to verify that all parts of your applications (this goes for all of your apps, not just your UVa app) are submitted! There's a little chart for each school that should show you the dates that you've submitted each component.
