what will I need if I'm ready to co-sign?
If the IDR applicant completed an Income-Driven Repayment Plan Request that was not part of a Direct Consolidation Loan Application, he or she will click on "Income-Driven Repayment Plan Requests" under "My Loan Documents" to locate and provide you with the Reference Number you need.
One more question, what if I'm completing entrance counseling to borrow a loan as an undergraduate student?
Then the entrance counseling will fulfill counseling requirements for Direct Subsidized Loans and Direct Unsubsidized Loans.
