Well, guess you won't be doing too much written communication. However, you might want to brush up on your English anyway. It will be less confusing for your professors to read your work if your writing is better.
I found one website that provide more information about MS in USA i.e:- MS and MBA in USA
Provide me list of website that are contain information about MS in USA
You need to take an english test called TOEFL or something like that before being able to apply to any US study program, you need to get at least 400 (if im not wrong) to pass it and no offense, but you sound like you'd get a 200 at best.
Work on your english first, then you can think about studying in the US.
