<p>how does Princeton notify you when they have received your application? Do they do it by email, and if so, how long does it take?</p>
<p>so you didn't use traking mail so you could look online?</p>
<p>i sent my app in online</p>
<p>They will email you saying they received your application. They will then let you know if anything is missing and they will send you a final email telling you that your application is complete.</p>
