17th or 18th ?

<p>When are international students expected to reach the campus; 17th August or 18th August? The FAQ's</a> sectionin housing department says earliest is 17th August and the Orientation</a> 2006 site confirms this. However, on my "Not that I am Enrolling" site it says:

You will be permitted to stay in campus residences starting Thursday, August 18th. If you arrive before August 18th plan to reserve off-campus accommodations.

So when should we come?</p>
