Payments through loan-type financial aid programs for undergraduate students will conclude with the standard period of study. You must apply for loan-type financial aid programs for graduate students anew in case you wish to receive loan-type financial aid payments after moving on to a graduate school.
You have two chances to apply for loan-type financial aid programs – the first chance around the fall of the academic year before your enrollment into a graduate school (around October) for reservation-based acceptance; and the second chance around the spring after your enrollment into a graduate school (around April) for periodic acceptance and urgent and emergency acceptance.
Submitting the form of repayment postponement will allow you to postpone repayments for loan-type financial aid you received as an undergraduate student for the standard period of study for your postgraduate program.
