My concentration is European and Eurasian Studies. Still nothing? Since it's past the December 20th deadline I'd say it is a good idea to send them an email.
I was accepted! DC campus. It is strange- I just received a scholarship award email (only $10,000) from them but still not a "go check the portal" notification email. Hope it all works out for you.
Once you click on your submitted application there should be a "status update" heading at the top of the page. They might still be updating applicants, as we haven't gotten emails yet.
