International Student - EA

<p>Hello,
I have applied Early Action to George Mason University on the deadline (9th November) but so far I have received no response from the University. As an international student, I realize that it takes a while for them to receive and process my application, but since I've read about a lot of students already getting accepted, should I be worried? I have submitted all required material but while checking my application status, seems like my IELTS score haven't arrived yet although I have sent them nearly a month ago! I have contacted the office of admission but they haven't been really helpful. Also, I would like to ask if any of you know whether international students receive their acceptance or rejection by mail or email?
