To increase your odds, you should ED2 at a college that offers it, after running the NPC and filling it out as if you were a domestic applicant, remembering neither Pell nor Federal loans are available to you (ie., you’ll have to remove 5.5k from the aid package and that amount will be the most they can provide.) Using this as a rough estimate will make it clearer which are the most generous.
Then, you can find a Fiske guide or Princeton Review’s Best Colleges (2022 edition and later is fine, ie., 2nd hand should be really cheap and perfectly ok to determine whether they’re the right “fit”).
Amherst College (not “university”, which is the state’s public university) is need blind/meet need for internationals and located in a nice area filled with college students. You can take classes at any of the 4 colleges in the consortium, ie., you could take graduate level math classes at UMass Amherst to complement their offerings if you wished (though many students admitted for their math major would enter with Cal1&2+multivariable calculus so they offer a lot of classes for someone entering with Calc1.)
Btw most European systems’ advanced math courses include calculus but also discrete math and linear algebra.
Williams is especially known for math so may be worth a 2nd look.
for Yale. You never know.
