Hello! I applied to MSc Computer Science @ University of Northern British Columbia and was accepted. I applied for a visa, however, I came to the gradual realization that I am not ready to leave my family and move to the remote city of Prince George, had a few depressive episodes, and since I was and still enrolled in my local university's master's program, I decided to postpone my plan of leaving the country and wait until my graduation. I subsequently sent a webform citing my depression and change of mind to cancel my visa application, but the next day my application OPRed. I sent in my passport and got the visa. The visa remains unused. My question is, how will this impact my future student visa application?
