Chance Me for T20: [Freshman, International, 1560 SAT, 4.0 UW GPA, Econ/Finance/IR] AUS Class of 2027

I’ve read all about this online, but there seems to be a glaring lack of information for international prospects. I am aware of one of my (significantly older) friends in my national team, which fences for UCSD (NCAA D1). They are the same nationality as I am, but they were an American resident with US fencing rankings. I am wondering if such a ranking is essentially a prerequisite?
