I agree with you Platypus, though I think the arguement they will play here is that since she has been in the country since she was 11, its not HER fault she isn't documented. My response is she is in college - so she is an adult and does in fact bear the responsibility to do what is necessary to be here legally.
As for her entry into college, my bet is that she never claimed citizenry. Most "higher education" centers now don't ask about a persons citizen status, and there is a push to have most state systems allow the "undocumented" to get in-state tuition even if they do not meet the requirements. Basically, say your illegal (regardless of your country of origin) and you get a benefit that a citizen of another state would not.
