Thanks for your reply.In my cases, my school has some special course codes for Thesis work. For example, I need 6 credits to be considered full time during Summer term, so I registered for a "dummy course" THES 906 which is equivalent to 6 credits of course work load. So in my transcript, I will always be full time. You should talk to your school international advisor about this and ask if they can provide some official explanation
I studied in University of Manitoba and they don’t have any “dummy course” but they just ask to re register in each and every term to maintain full time status that is reflected in my transcript as well.
BTW I have asked university if they can provide me letter saying that I was a full time student throughout my studies.
Thanks again
