Although I am sorry for your current situation, the priority is to educate American citizens and legal aliens. Why would we try to educate those staying illegally when we can’t even guarantee education for law abiding, tax paying citizens and residents?
If it is possible, I strongly advise you to return to your home country of Brazil and pursue higher education. If you succeed, your chance of pursuing your Masters of Doctorate becomes higher here in the States.
Best of luck with your endeavors
