<p>I want to apply for housing just so I can get a good priority number without waiting on some of my friends who are still undecided, so can I submit a housing application and change my roommate choices later after I submit it once they decide on their school?</p>
<p>Yeah I think the best thing to do is to go ahead and apply for housing so you get a good number, despite your friends. You know you want to go there so that’s what really matters. After you complete the housing agreement you can always update things without altering your priority number I applied Dec 9 and my number was 2381, so numbers are filling up fast. Good luck! :)</p>
<p>Yep! 
You can change both your roommate and dorm preferences until the end of spring (around the first of May I think).</p>
