Esql, I think you are in a great hurry to enter USA. Don't do that. Take your time and get into a good school with scholarship. I think MS in computer science will b better for u since you have an IT background and it has better scope too in USA. To find colleges, go to collegeboard.com. You can filter colleges by your major, tuition fee, location, and yes GMAT required or not. Since, you are going to USA for your masters degree, you should not blindly jump into. For you, it will be easier to convince the consular if you take computer science as major.
Good luck to you.
