I think that you might want to wait a year. In the mean time think about what you want in a college or university. Do you want a large school or a small school? What sort of location do you want to be in? What sort of climate can you handle? What are you likely to want to major in?
To give you something to think about: One daughter attended a small school (approximately the Canadian equivalent to what in the US we call a “liberal arts college”). Her first semester freshman year she had two classes that each had 15 students or less. The largest class that she ever took over 4 years had 90 students. She got to know her professors which helped her to get research opportunities. My other daughter attended a larger university which had larger classes but a much wider range of majors. She ended up with two majors (two different bachelor’s degrees) both in a major that the first smaller school did not even offer. She also was able to take advantage of the larger school’s having a farm within a couple of miles of campus. In general smaller schools are likely to have smaller classes taught by full professors, but larger schools will have more resources and a wider range of majors available. The availability of unusual resources such as a farm, a nuclear research facility, or a library dedicated to music is going to vary greatly depending upon which university you attend. Of course there is a much wider range of unusual facilities that some universities will have and some will not.
Cornell for example has 25,000 students and is in a snow belt. I was visiting one time when it got at least two feet of snow in one day. Stanford has 17,000 students on a huge campus in a suburban area in a warm climate and to the best of my knowledge it has never snowed there (when I got my master’s there it did not rain either). Dartmouth College has 6,000 students in cold rural small town New Hampshire. Harvard University is right in the middle of a city with lots of restaurants and things to do right there (when you are not busy studying). Harvard and Stanford are also close to large airports with international flights which might make flying home easier than it might be if you are at a more remote location.
What you want to major in will matter quite a bit. One relative graduated with a degree in dance. I would not go to MIT for dance nor would I attend Julliard to study mathematics. From your original post you appear to be interested in and good at quite a few different fields. Different universities will be better for different potential majors.
This is also important. Finding an affordable safety in your home country is much more important than finding a good fit among reach schools where you have a 1% chance of admissions (and that only because you are an exceptionally good student).
