Last Friday's party was reported to have featured an Asian theme, but university vice president of student affairs Larry Moneta said the title was changed to international relations after some students complained.
An Asian student group filed a complaint and held a protest rally Wednesday.
Pictures posted online showed people attending the party dressed in Asian-style clothing and a greeting that mocked Asian dialect.
Kappa Sigma executive director Mitchell Wilson said the national organization will investigate the party and take final action based on the outcome of that probe.
Moneta said the university is considering unspecified action.
