@Xiaomau82 hello po, uni ko po nag-arrange ng OSHC ko para mas madali. but i think if you want to get it on your own, you just need to present iyong letter of offer so they can calculate the premium. if ngPR before you finish your course, they will reimburse a part of the amount paid less fees.
Required po to pay the OSHC in full depending on how many years you are going to finish your course. So kung 2 years po iyong program, 2 years din po dapat may OSHC kasi isa iyan sa requirement ng DIBP, na you have OSHC for the whole duration of your program.
