Hi, I would like change working holiday visa to visitor visa inside Canada, I checked the official website, I must apply 30 days before my working holiday visa expire, but the process time is 50 days if I apply online, so which one is correct? What if my visa expire and I didn't get the approval? I can still stay until I get the reply or I must leave Canada? Also, is it if I get the approval earlier than my working holiday visa expire, I can't work anymore?
