Hello there—I would be happy to offer up some guidance for you here. Yes, you will certainly have a shot at an MBA in the US. If you can break 700, you should be in the top-50 range! Now as you get closer and closer to 760, 770, 780 etc. you will be able to rise up the ranks into the top 30, top 20, and top 10. But for you especially, given the fact that your school is not a top-ranked one (and you have a great work experience either it sounds like.) So the GMAT, in cases such as yours, becomes VERY important. If you can do very well in that test, you will have good chances this year. So get a 760…and you will be in business!
