If you applied to a school with Early Decision and they have admitted you, you need to withdraw your application to UVa. To withdraw, just email uvaapplicationinfo@virginia.edu with your name, high school, date of birth, and tell us that you want to withdraw your application.
Some people are emailing admission officers directly, but remember that doing that will slow things down.
Congratulations to those who have come to the end of their college search!
