I have no specific bias for or against IMGs. I'm currently in the process of trying to move to Canada and practice - I'll be an "IMG" for them.
Let me say this with regards to Emergency Medicine: Essentially all of your practice will involve the elderly who are old enough to have communication or comprehension problems because of their age or mental status, the underclass of American society (or their children) who have communication and comprehension problems because of their station and attitude, and the critically ill who have communication or comprehension problems because of their clinical status.
Because of this - and because of the importance of communicating critical actions to staff in a clear, concise, and timely way - absolute fluency in the English language is a must in Emergency Medicine in a way that isn't quite as important in other fields.
Aside from that your numbers look good.
