You need to contact MIT if that is the place where you are applying. They require the CSS Profile for consideration for need based institutional financial aid. Their financial aid office will tell you what they require.
IIRC, the Profile form does not have qualifying questions to become an independent student.
But ask MIT what they want. They will tell you.
As an aside…the acceptance rate for international students at MIT is in the low single digits, so please…make sure you have other schools in mind. 95% or more of international applicants are denied admission.
