Choose white if your last name is European. Identifying yourself as Asian can only hurt in my opinion. Asians are hurt more at the undergraduate level because the admissions process is less numbers based. From reading the recent articles about the lawsuit against Princeton, one belief is that if you identify yourself as Asian, they'll assume you're quiet, unassertive, and a "math-grind" unless you prove yourself otherwise.
thanks for all the opinions/advice. yeah, last name is polish (gniadek). i was a philosophy/linguistics major, and i would think being a science major would be easier since there are actually objectively correct answers. kills self, which school is your scool? thanks!
