Hi everyone! 
I am also looking for some advice on the Science Po PSIA program. I went to an okay american state school here in Oregon with a 3.6 GPA and a Political Science major...Minors in French and Business. I have studied abroad in France and taught in France.  I am currently a legislative assistant but have intern experience with a US Senator, World Affairs Council, and others.   I'm worried about several things: I did not attend an ivy league school, I don't have any close professors so my letters of rec will be mediocre probably, I never wrote a thesis, and my GPA isn't amazing.  I really want an international career and I understand PSIA is competitive. Do you think I'd have a shot at getting into the program?  Thanks for the feedback!
