I think this is a nonissue and that you don’t need to contact the Admissions Office. You won’t get rejected because you’re Asian or White, and at the same time, you won’t necessarily be accepted because you’re a URM. Case in point, me when I applied ED to Columbia University (and I’m a URM) - I was deferred.
As long as you’re qualified and unique, you have a shot. I think people are overestimating race in this admissions process.
