Im actually applying to some schools there, ive been there before and i felt very safe, the people are generally friendly, aand as long as you dont threaten to kill people you will not be harmed. Although this is because the maximum amount of time i stayed in America was 2 mounths, never more than that. I generally perfer countries like singapore more, but ive actually lived there and i never tlived there in america. Nevertheless, please apply to america, they have a great educational system that focuses on your character and persoanlity traits like creativity, and unlike oher schhools, they consider those parts equally important as your academic achivements.
Good luck
peace
