It really depends upon the school. Many schools accept students whom do not have to declare a major until the end of Sophomore year. Harvard is one such school.
But there are other schools that admit by major as an in-coming Freshman and due to the competitive nature of some of these schools and majors, if a student is not a direct admit into their preferred major, it can very difficult to switch majors later. An example is Engineering/CS at many of the California UC’s.
You should be able to look up the admission process for any schools of interest on their website to see how your daughters major will impact her admission chances.
