<p>First, submitting a Wilson fellowship application, or not submitting one, will have no impact on how your application for admissions is reviewed. It says nothing of your interest in the school or research for that matter … and it is completely optional. Your Wilson application is separate from the admissions review.</p>
<p>As far as submitting a late application for the Wilson fellowship, you can try to do so but I can not be confident in saying it will be accepted. My suggestion is to submit your Fellowship application ASAP and provide a written explanation for one the information was not submitted by the deadline.</p>
