How long to wait?

<p>Hello, I emailed my EC about a week ago. I have no response. I'm thinking I should call him. Is their any suggestions on how long I should wait?</p>

<p>When contacting your EC via email to set up your interview please enter "MIT Interview Request" in the subject field.This is to help identify your message more readily should it be mistaken for spam.

<p>Oops. But I also remember reading a post from one of the admission blogs, saying to wait a week or to. But thank you anyway.</p>
