hi SMH. you most definitely cant expedite the process for any school. One thing you can do is ask for an extension to the deposit deadline. I have seen many cases where an extension of about a month was given. be creative with yr reason for extension and you should get one.
in case you are not given the extension, then the only thing you can do is to wait for a phone call or email from ross during the 1st week of march. ross contacts all its admitted students before the decision deadline to give them the good news personally. if you are admitted, then you will definietely be contacted before the deadline. if not, then most likely you are WL or ding....so then you can go ahead with the payment to the other college....
hope this helps...
