I applied for study visa around October 2021, I got a mail my application was approved and I went for medicals in march 24,2022. I later got another mail to send my passport for visa stamping which I did on April 4, 2022 through DHL. Till now no response for pick up. I have sent several mails. It's 4months already. Hope my application is not been rejected and am I not banned from entering Canada again?
