Hi,
I'm from the UK but I know quite a lot about the US as two of my brothers are studying there. To be honest, a 2.82 GPA is not good enough to get a scholarship in a top engineering department. Depends on which unis you're aiming for. If you're looking at MIT, Caltech, Stanford, etc…. then I'm afraid it's not good enough. That being said, for other universities, they may consider other parts of your application that would compensate for the GPA: can you get really good references? do you have a really good personal statement? These things would counterbalance the GPA but you should be realistic about the kind of university/department you're aiming to get into.
