Changing Application to Early Decision

<p>I applied to George Washington U Regular Decision, but since submitting my application I have visited the school and decided that I definitely want to go there. Do you think if I call the admissions office they will allow me to change my application to Early Decision II, and do you think this will positively or negatively affect my chances?</p>

<p>If it's before the deadline, sure why not?</p>
