Email to potential advisor after submitting an application I applied to graduate school in US about two months ago and I am still waiting for my result. I was thinking may be it is a good idea to email my potential advisor again and asked them whether they have looked at my application or what is the status of my application?

Can you please tell me how to start this email? How should I politely ask about status of my application?
It is uncommon to ask a faculty member about the status of an application as most of the time it's the admission staff who handle this kind of inquiries. If the faculty has said that you can email him/her, then it may be fine. Otherwise, check with the admission staff.
