I'm applying for nomination to my 3 congressman. I have candidate files open for the USAFA, USNA, and USMA. I really only want to go to the Air Force Academy (I don't think I'll even complete my other files). My question is, do the congressman nominate you to a certain academy, or is it a nomination to any academy? I don't want to be nominated for the USMA or USNA when I'm really only applying to the USAFA.
