I got the XG number and could not link my application to GCKEY as well. I don't know how long it will take to be able to link it!!!Hi. Thank you so much for the all information. It’s really helpful. The agent from Ircc told me the same thing. Remove the X and you can link. But not now. When they start processing your application they will remove X and send you an email. So I tried many times but I couldn’t link like he said to me. Thank you.
