I did my interview on Thursday and I was eligible, but I realized the dates I visited Canada in the past are wrong can I change that ? I also did something I'm not supposed to do when I studied English I was on visitor visa and I studied a year I didn't know about what I did was illegal until after I got my certificate saying I graduated on dec but in my form I said January to June what should I do ? I'm afraid this will impact my case please help
