Harry Potter star Emma Watson is taking her U.S. college plans to the highest level by touring one of the country's most prestigious universities.

The young actress was spotted visiting the campus of Harvard University in Massachusetts last week for an open day.

University officials are refusing to comment about their celebrity guest, but insiders have confirmed the Brit inspected dormitories and the admission office.

Watson hinted about her plans to study abroad in an interview earlier this year.

She said, "I've applied to a few universities for next year, including several American ones. If I do go there (America), I will do a liberal arts degree, but if I stay in the U.K. I'll do English literature."
