Now where, might you ask is there a story for student journalists in that?
Let's start with just the international community at a college campus. What are the reactions of the students from Country X about the ranking their home country got? What is their own perception of corruption in their country AND in the USA? What do they think should be done about the problem of corruption? What do they think are the main effects of corruption on their countries?
From there, start talking to professors from other lands. Professors who are studying the most corrupt countries on the list. Get them to talk about the hows and whys of the problem.
Boom! A local campus story with an international angle.
Now step outside the campus and talk to the local immigrant communities. Ask them the same questions you asked the foreign students.
Boom! Another local story with an international angle.
