Hi , I did this study visa application for my brother and made a mistake in form 1294e The question no.9 said “ country or territory where applying “ I understood it as “ country and territory where applying to “ so I marked NO ( I am guessing it’s country where applying from ) How can I inform Canada ? Can I raise webform ? Can this lead to rejection ? Also , In form 5257 , they asked for UCI number , I didn’t have any at that time ! It was suppose to be left blank ? Kindly reply Thanks
