Yes, I see now that you specifically included your intent to major in physics in your original post.
In general, the terms in which you have described your schools of interest may limit your chances of studying in the U.S. For example, colleges that would be superb for the undergraduate study of physics and mentored research in physics, such as Pomona, Williams, Hamilton, Haverford and Reed, may not currently be within your consideration. In other words, if you were to select the right reaches, instead of those you have seen on a limited top-20 list, your search could work out really well for you, at least partly because you would encounter less competition from other international applicants. In choosing schools to which to apply, you may want to look into some of the awards presented by the American Physical Society (examples below).
