OP needs a place to attend and there will be trade offs they may have to make and those usually start with financials.
IR is a subset of Poli Sci. Some break it separately. Others call it out as a focus area of Poli Sci. It’s semantics.
Another thought - IU, Arizona, and Ole Miss are the three federally supported language flagship schools I think Ole Miss will hit budget but need to validate. IU and Arizona won’t but the Language Flagship might provide money. You might reach out to all three and ask.
