Hi, I'm currently holding student visa. Due to personal issue now I'm returning back to home and not wish to continue my studies in Australia (courses still on-going, CoE still valid). The only thing I'm concerning is that I didn't withdraw from my college prior leaving back to home. I heard that I can cancel my student visa back at home, is there any effect or anything I will be facing in the future when I visit back to Australia? Or can I cancel my student visa without withdrawing from my course?
