I have no idea about Colorado State University, but being a state university it shouldnt cost much... however you are just moving into the U.S., so you will be out of state everywhere - so even state universities may cost more. Check their websites.
I go to a CUNY (City University of NY) school which are really, really cheap. Few of the major colleges (Hunter College, City College, Brooklyn College) are pretty good, but not that very known. And being in the city, you don't really experience that college town experiences and stuff, if it matters for you. Check it out nevertheless if money is too big of a issue for you. But, living in NYC is crazy expensive, so keep that in mind, as I am sure other cities are.
Also, you may want to choose your undergrad where you want to become in-state for when applying to vet colleges. Say you want to apply to CSU Vet School, Colorado State would be a good idea. Of course, you only become in-state if you have a green card or citizenship. If you are an international student on a visa, you stay out of state even if you live in that state, as far as I know.
