<p>It is based on when you submit your housing app, but it ALSO requires the fee payment first. You need both for the date to be set, then you can change it after as many times until June.</p>
<p>As I recall, catherineee is entirely correct. Oh, and don’t pass up a chance to get Snell-Hitchcock just because you’re not submitting immediately.
