I didnt ask you to prove anything to me but to back up your claim which is not true, imo. It's irony that you explode after your rejection. You couldn't define what "important country" means and you include "all English speaking countries", I guess even third world countries fall in. My point is your statement is too wide and vague. You could at least narrow down your hypothesis to make sense. All the best with your studies in US....As I told you, they are posted on official immigration website. You can check if you want to. I don't have to prove anything to you.
