JSA Summer Program at Georgetown for an International Student

I’m thinking of applying to the JSA Summer Program at Georgetown for the 2016 summer, but as an international student I’m finding it hard to find information about other requirements I’d need to consider for my application.
Is it harder to get in not being from the US? Am I even eligible to apply? No info in the internet tells me otherwise, yet it doesn’t confirm it, and the email provided by the JSA webpage doesn’t reply to my inquiries.

PS. I’m from Dominican Republic.
