What state do you live in, and what are you wanting to study?
On all your highly selective schools, check for the way they classify URM. You may be able to get your Cherokee Tribal acceptance papers in time or can have the ‘pending’ determination settled after your initial application submission.
Look to how your story/you add/contribute to the various selective schools.
Are you looking for almost all costs covered due to low income and the meeting full needs from various schools?
It sounds like you have had a lot of struggles in your life, and you hopefully can find a school where you can happily thrive. You are looking for a big culture shock compared to where most of the study body is coming from - maybe that won’t bother you. Friends and ‘a tribe’ are important to students.
