You know, those aren't the only two options. There's a lot of places in the world where the OP could study where it might cost more money than here but not ludicrous American amounts (Spain, Canada (depends on university), Mexico).
In Canada she'd be able to get a job on campus where she'd actually make some cash towards paying tuition and living. And be in an educational system similar to USA -- ie course loads / exam styles. Here a lot of North Americans are just not used to the exam style (which by the way to the OP, in a lot of courses are going to be oral exams taken over various days).
Then there's Argentina. Different language, different system, and yet, cost of living not dirt cheap. In fact a lot of things surprisingly expensive. But any job you get you're going to be earning in pesos. So you'll have the broke student experience but even shittier -- especially because unlike your classmates, you won't be living at home getting free meals from mum and dad, who are probably also kicking in some pesos to allow the kids to go to the boliche, or they have a job as well. The only advantage to Argentina is the "free" tuition -- which I can't even remember now, but since the OP doesn't have a DNI doesn't it mean that it's actually not going to be free at all? Not sure how it works with UBA. Oh and remember that whole pesky thing of having to redo the last year or so of Argentine HS before you can get in -- which I'm still blown away by, and which my husband is convinced is not true, but seems to come up on this forum a lot.
I don't know, being 100k + in debt sucks, but there are better options that Argentina. Who the hell knows what will happen in 2015 as well. I would not want to be a broke student with no family in Buenos Aires that's for sure -- there's got to be a lot of better options out there. Guadelajara? Ecuador?
Whaddya know -- I just googled "countries reasonable tuition rates international students" and guess what, there are better options:
