Petitioning in to Honors Program with registration

<p>My son was accepted to the SPA at AU! He was not accepted in to the Honors program. I was wondering if any current students, or an Admissions rep could tell me whether it is possible once the May 1 reply date has passed, if the school has less enrolled Honors students than anticipated, they would reconsider candidates for that program. Would it help to send a letter with his registration petitioning reconsideration?</p>
