Plus, you want to major in, and apply to popular, crowded majors at the same universities, where every student applies. The seats are finite, and, “fit” is really an issue at these elite schools. If a university wants an oboist, an artist, or a green environmental “farmer”, then that’s what they’re going to search for and select.
I don’t mean to minimize your accomplishments, but your school experiences are very similar to the thousands of your countrymen who are applying to US universities (i.e. tutoring a computer language, starting a science-based club, and playing tennis).
Read some of the posts (here on CC) from your countrymen, who list very similar activities that they believe the schools want. It seems as though there is a checklist somewhere.
Apply wherever you want, but “spread the wealth” by applying broadly to schools that aren’t Ivies. Lots of students are shut out by the Ivies. There just isn’t the room for the hundreds of thousands of students wanting seats at the Ivies. Apply to the safeties in your country.
