OK - note my Syracuse story was to show that everyone (a bit of an exaggeration) at GW, American and Georgetown wants to work in government but most will end up in companies, managing restaurants, investment advisors, etc. Sure, more of them will land jobs that kids from other schools because they have more kids on this track.
In the end, it’s your initiative that will matter. Kids from schools all over, known and all know, find success. Not only is there international government but local, agencies, etc. At Buffalo, you can probably find international experience with Canada.
To me, I’m going to save money - in this type degree. You have great SUNYs - Bingh, Stony Brook if you want to be closer to NYC, Albany (the capital) and others.
Additionally, if you look at schools that are “beneath” you, you will find monetary opportunities.
So let’s look at the two you pulled and not sure why you chose UWM - but you cannot assume you will get in there. Your GPA is a bit iffy for them although your ACT will help. Not sure what kind of rigor you have. I would add Indiana to your list - if you want a Big 10 school, it’s a safety for you although maybe not a scholarship and depending on the language you want to study, it will be better. It has an entire school for you - Hamilton Lugar.
GW - is a reach for you. You have to demonstrate interest too - so get on their email list, sit it on a session.
Are you sure your parents want to spend the $$? You say money is not an issue - but you are not them - and this is a liberal arts degree that does not lead to a profession.
Given your GPA/ACT, here are some other solid schools you may look at besides IU - Pitt (likely), Florida State (reach), Miami Ohio (safety).
If you’d like smaller/LACs, look at Dickinson (target), Gettysburg (Target), Skidmore (slight reach) and St. Lawrence (target). Elon might be of interest to you.
A school like Delaware will give you money I believe.
Take a look at CUNY too - as you’d be in NYC (think the UN) so Stony Brook might be good or even Hofstra. U of Denver is a possibility for you and has a wonderful IR program.
Finally, I say College of Charleston could be a good one - lots of opportunities if you seek them. I imagine the same could be said anywhere.
Wisconsin is not high ranked in IR so I’m not sure how you pulled it in - but that;s ok - it’s a great school but I’m not sure you’ll get in.
Good luck.
