In 2012 & 2013 my student visa application refused by USA embassy. They did give visa refused seal in my passport. But there is striker in my Old passport which indicating i faced USA embassy. Now i'm applying for Canada TRV visa with New passport where no refusal and three counties visa available. Now if i write in visa application that i never refused. Is it possibile for them to find out i was refused by USA embassy? As far i know No embassy share there information with others. Please share your experience.Thanks.
