I'm particularly interested as an international who did my undergraduate degree in the US and is currently working in management consulting. Would be great to hear thoughts from Asians/Asian Americans who've gone through the process or from non-Asians who have a view of this issue and have experience to share.
My recommendation is not to focus on "behavior/traits" that hold a group of people back in the American corporate environment. But to focus on the attributes that succeed in the American corporate environment. There's a very good book by Stephen Covey called "7 Habits of Highly Effective People" - that will help.
