I usually just read along on CC, but I’m chiming in here because I really hope you find a way to safely and affordably go to university and stay in this country. Many years ago, when I was at Georgetown, I knew several undocumented students, who reported being well supported by the university, financially, in terms of help with connecting to legal support, and also with the specific challenges of being undocumented in college (which have only gotten worse since then).
They have a website dedicated to undocumented student support, undocumented.geogetown.edu
You should also check out the Georgetown Scholars Program, which helps support FGLI students (regardless of immigration status)
Georgetown doesn’t necessarily have a reputation for being the most generous with aid, but I’d encourage you to reach out to some of the people mentioned on these sites and discuss your situation as much as your comfortable with.
As others mentioned, checking out Jesuit universities more broadly may be helpful.
