I found more specific information about the proposal. Cap for Parent PLUS is $26,500 (the difference between the aggregate amount that dependent & independent students can borrow). The cap for Grad PLUS is $50,000/year and $100,000 aggregate (total that can be borrowed in Grad PLUS overall). But it also proposes that there will be a single loan program for grad students, so that would eliminate the unsub (which currently is limited to $20,500 per year).
FSEOG would be eliminated. FWS would be cut in half.
Trump proposed consolidating the income-driven repayment (IDR) plans into a single plan with a discretionary income cap of 12.5%, a 15-year repayment term for undergraduates, and a 30-year repayment term for graduate students. The standard repayment cap would be eliminated. This would only affect those who borrowed their first loan on or after July 1, 2021 (further confusing the loan repayment landscape).
