I'm confused about whether or not I should have cancelled my Visa extension. I've previously had two education visas through a language school (Language Express), 9 months + 6 months for a total of 15 months. I left the country about 4 weeks ago, my extension of stay expired while I was away and about two weeks ago I came back on a 30-day exemption.
My school didn't tell me anything about needing to cancel the extension, and I didn't cancel between my first and second visa. Only after reading online and asking the staff at my school they've told me that I need to cancel and they've told me that they will prepare paperwork for me. I was told though, "don't worry, it's fine. Can cancel later."
What process do I need to go through now, and what sort of trouble if any might I find myself in?
