The Div 1 Ivy schools do not offer any sports scholarships, so they wouldn’t be the schools you would consider, especially since I believe most do not offer financial aids to international students. The non-Ivy Div 1 schools will often be able to offer some degree of scholarship, as SevenDad mention, if only a portion, but sometimes a full ride depending how desperately they want the athlete. Unfortunately right now, most of the Div 1 schools most likely already have committed their recruitment slots, so you may not have much to “choose” from. But it wouldn’t hurt to approach the coaches to ask about being recruited. I would send out emails asap to the head coaches of all the schools you are interested in, with your son’s academic and fencing stats. Perhaps, if you are lucky enough, one of the schools may have a recruitment slot available to consider recruiting your son. Good luck.
