Yes - we had stopped completing the FAFSA once we stopped (correctly so) being offered subsidized loans, but restarted now, because there was a “new” facet and she could apply “independent”.
However, as a grad student, those subsidized (college) loans can be further deferred during the new “in school” years. If you fill out a FAFSA, the new school ID is supposed to trickle down, but otherwise your loan processor will have a downloadable form that the grad school registrar will sign and the loan will continue to be deferred the next n years.
