Hi, all. I am recently in the process of applying for a Canadian study permit in the UK. I am a Chinese national. On the document checklist they put IMM5257 as an optional material. I already have a prior V-1 multiple-entry visitor visa that expires in 2027. Do I still need to fill IMM5257 as part of my application? I am asking because I will be abroad for some time and would not be able to submit my passport promptly if the London embassy requires it, and would like to avoid this type of trouble if I could. Many thanks in advance for your guys' help and advice!
