Have you checked out Questbridge? It’s an organization that helps low-income and first-gen kids with admissions to top US schools. Here is their page describing eligibility https://www.questbridge.org/high-school-students/college-prep-scholars/who-should-apply. It’s a great program that may give you some early decision options (multiple apps rank ordered vs. only one) that aren’t generally available. Also provides help with apps, financial aid, sponsors visits to universities, etc. And you apply as a junior, so good timing, I think.
