【求助】department发拒绝会经过graduate school吗

一个申请了很久的项目今天忍不住跟进了一下，
小蜜说：[size=14.6667px]Your application is in process within the graduate school.  You should hear something within a week or two.

想问问着算什么。小蜜也没说recommended to the graduate school，而是说了一个很模糊的现在研究生院在审核。
如果department同意了当然需要graduate school approve, 如果拒绝的话也需要研究生院同意吗？
