I couldn’t find it at their site.

“Because Penn State cannot offer financial assistance to undergraduate students from other countries, an international applicant must certify that sufficient resources are available to cover expenses for the first calendar year at Penn State, exclusive of travel expenses. You must also indicate how you will meet your expenses for subsequent years.”
Basically – it appears that there is no need-based financial aid. I am not sure if international students are eligible for merit aid, but those types of scholarships are not as common at Penn State, and usually small.
