All roads lead to Rome. If you can find a business-related position with your bachelor degree, and you are happy with the position, then go for it; if you can't, then probably go to the US and experience an international environment is a good chance. During the economic ressession, good to stay on campus. An MBA application is a balanced evaluation. A master in US does not necessarily have advantages over a domestic bachelor, in many cases. However, an experience in the US at early of your life will definitely help you get a more open mindset along with a richer experience. Good luck!
