When I sent in my application to my Congressman for a Congressional nomination interview, I put the Air Force Academy as my first choice and the Merchant Marine Academy as my second. I want to change it to Naval Academy as my first choice, then the Air Force Academy as my second choice. My Congressional Nomination interview will be in two weeks and my appointment time is already set, is it too late to change my Service Academy preference? And would changing it be seen as a negative to the interview panel? Thanks.
