I just looked at your previous post and you appear to be a competitive applicant. I think being Japanese should be a (slight) plus because there aren’t many applications from Japan to US colleges (vs. South Korea, China and India). You also have an interesting background. So, I would encourage you to give it a shot.
Financially, Swarthmore, Duke, UNC-Chapel Hill and UVA also offer full merit scholarships to international students (but highly competitive) and might be worth considering. If things don’t work out for undergraduate study, you could try again for graduate school.
Good luck!
