Re: My GRE score
I would say you will have a fair ~ good chance depending on your grades in the core engineering courses you took at your undergrad level.
In the US, admission policies not only differ between university to university, it even differs between colleges to colleges (business college vs. engineering college) and in most cases between departments to departments (civil engineering vs. comp. sci for example). So you have to do research or at least find some alumis from your current school who are now studying abroad to fill you in about the details of the university they are attending.
Regarding scholarships, if you don't get funding for your first semester, you should definetly consider universities, actually specific departments, that has a lot of funding available. Because there is a good chance you might get funding/scholorship in your second semester.
The idea is that if you do not have any offers of scholarship for your first semester, you might be better of going to a more expensive school that does offer a lot of funding than going to a cheaper school that does not offer any because if you are a good student, in the long run, the one with the funding sources will give you funding and will end up costing less than the more expensive school.
