Re: schengen visas
when you leave you just go through US customs, they don't care if spain gave you a visa or not. The only problem I could see you having is if you got mugged or something and had to deal with the police, and even then I bet there is a good chance they wouldn't check your visa.
your biggest problem might be if your school checks, but if you're already enrolled I think you should be fine. It'd be worth checking with someone at the school you trust.
