Foreign Tennis Player Issues I suppose there's an argument that a court could rule that the intent of Title IX (in regards to athletics) was to protect women in America by effectively reserving sports on US collegiate sports teams for them; therefore, international players taking those slots is a violation of legislative intent.
I doubt anybody's ever going to put limits based on citizenship status or birthplace -- because those are politically charged and have the potential to limit folks who've been in the US a long time -- but I could see some sort of NCAA rules about limiting nonresident students (like how public schools already calculate tuition) or requiring some percentage of teams to attend US high schools.
But since I'm not in touch with what the national data is like, I have no idea if this is a good idea or not.
