<p>I think i remember reading before that if you do some significant internship or win some award after you submit your app, you can contact admissions at your schools and let them know about it, to hopefully have them put it to consideration when they read your application.
Would an internship with a congressman be worth informing admissions about?</p>
<p>That doesn’t rise to the point of an update, IMHO. Have a great time, though and good luck</p>
