You may want to read this thread: How hard is it to get into MIT as a graduate?
In particular, this quote:
"The EECS program admits about 5% of those who apply. It is really spectacularly difficult to get into.
It also requires a minimum score of 7 on the IELTS, unless your first language is English, you have been been studying or working in the US for two or more years, or your undergraduate institution uses English as the language of instruction."
There's no formula for admission. I'm also interested in EECS at MIT, and from what I've heard, they don't care much for the GRE, as long as you take it and do well on it. Its math section is much easier than the SAT, but its English section is much harder. There are so many applicants with perfect math GRE scores that having one doesn't guarantee admission by any stretch of the imagination. Then again, nothing does.

In short, do research and internships. Be passionate. Try very hard to get into a position where your research will get published. Take challenging classes and keep your GPA up. EECS grad admission is extremely difficult for domestic students, let alone internationals.
