MIT does not admit by major. If you are accepted, then you can major in anything that you want to. You pick your major at the end of your freshman year. They also have a “math with computer science” major in addition to their normal computer science major (which has somewhat more EE than I would have personally wanted). It is of course a reach for the strongest students and out of reach for everyone else.
I expect that some others of these schools do not admit by major, but I could not tell you which ones. It would take some digging on each school’s web site to figure it out (unless someone here can comment for each school).
