Of course, if you are an engineering /CS major, unless you are very, very good at learning hegemony, you should give up. Although UCI is different from Los Angeles or California, it is still the University of California. Engineering will be more difficult to read.
Finally, double degree and double major are different concepts. A double degree is usually a degree, and then there are two majors on it. For example, Bachelor of Applied Mathematics and Economics. A double degree is actually two degrees, which usually requires a bachelor of science and a bachelor of arts, such as a bachelor of science in applied mathematics and a bachelor of science in English literature. In fact, there is not much difference in essence, but if it is a double degree, it is usually necessary to really complete all the credits of the two majors. Double majors, generally only need to meet the GE requirements of one major, and can give some credits to both majors at the same time.
Finally, it is usually impossible for engineering students to double major. Carl, only one principal took a double degree in EECS+ Chinese last year. It is generally possible for science students, but it may not be big. Usually, the second major is either language or very related to your major. Moreover, liberal arts students usually have more time, and they can often be seen to double or even triple major. The feeling of triple major like Asian studies+Chinese+communication is completely possible, and in fact, many people have done it.
