At elite schools w high avg SAT scores, the admitted applicants w low scores typically have some “hook”. U have no “hook” (URM, athletic prowess, extraordinary dance/music talent, development case, national-level science competition winner, etc). The extenuating circumstances u listed (immigrant, 1st gen, etc) will be shared by many applicants. And on top of it, your SAT scores, while average nationally, would put u in the bottom quartile of the schools on your list.
Have u looked at any SAT-optional schools?
