I have my student visa, approved, all plans made and everything and I'm supposed to arrive soon, but I'm seriously doubting my decision. I don't want to waste my plane ticket or make a mistake and miss an opportunity, so is it possible to go there on my student visa but if my doubts are confirmed and I want to come home, would it be possible? I will still report when I arrive but if I come home within a few weeks, is that allowed? and will I need to cancel my visa? Because I might want to travel in the future but on a tourist visa.
