Just send an email to consul@kuwaitembassy.ca and they respond within few hours. They responded to my email saying; you don’t need qr code, your certificate is stamped by the embassy. Their email is very clear evidence that my certificate is issued and stamped by the embassy.Thank you for the reply.
I sent email to embassy (good conduct email) two times and no reply. Hence I submitted to IRCC the clarification letter attaching the copy of the emails sent to Embassy. Also informed them that if required, I can send the original received certificate to IRCC, when requested. Waiting for their reply. Hope they will accept the clarification since its genuine and I have attached the emails sent to them along with courier delivery details, copy of demand draft to embassy etc.
Also i wrote to them that I cannot request another Good Conduct certificate as my current certificate is valid until March 2025.
