EE/PhD 关于如何回复老师

At this time, I do not have any open positions for the coming Fall yet.
There are still some pending projects which may come through, but I will not
know about their outcome before June.
I am not sure if you have received any decision yet on your application from
our graduate school, but when you do, try contacting and checking with me
again.

Best wishes,

这是一个前期联系不错老师的回复  这种我是应该继续等待他 还是去联系系里的其他老师

if the admission decision made by committee, it doesn't matter. you can contact the prof. after you get AD
if not, I think you should contact others to increase the possibility

So the most important part is try to figure out the admission process
