His point is that schools in US will understand your transcript and the educational system, whether it's modelled after the Brits or the Americans.
I would wait on picking schools until you have your GMAT score. It won't be a determining factor but might help you narrow down your choices.
You can also start looking through the essay questions from potential schools and see which ones interest you. The questions can tell you quite a bit about the schools and their styles, generally.
Thank you for your advise. I am preparing GMAT exam and trying to get the best score as I can. I do not know I can get 700+ or not, but I will try my best to do so.
