What are my chances?

Im a rising senior from A French school in Turkey. I really want to study in Gallatin because its concept really thrilled me. I want to do something about politics and human rights. Actually,my long term goal is working in the UN,therefore,human right studies is essential. But frankly,Im confused. I also thought about applying to CAS and study politics major and middle eastern studies minor in order to learn arabic but I heard that getting into CAS is more difficult. Anyway, right now I just wanna learn my chances about getting accepted to gallatin. I also wanna learn about the student profile of gallatin.
