I agree with you 1000% TC. I am an engineering applicant myself, but I have no foreign languages. A lot of people here most likely never taken all Calculus courses, Differential Equations, and Calculus physics 1 and 2 to know how much work all of those courses take. It literally takes 2 years in college just to complete those courses I mentioned, which is how long one stays in a community college for to getting their associate’s degree. Maybe if you were majoring in liberal arts, communications, or women literature, then it would be plausible to study a foreign language. But most of the people here will not be rational since a lot of them are elitists.
As for your question, I know for a fact that Berkeley does not require foreign language for engineering applicants. I know this for a fact. I am sure MIT and Cal are the same way as well. But beware of some universities who make it a requirement even for engineering students such as UF. That is the main reason why I did not waste any time applying to that university. Anyways, good luck and I hope this helps.
