Hello there,
I got my 2nd RTD, at the time of application I requested to send me back the existing old RTD cause there is valid US visa. Unfortunately, they didn't gimme the old one back, sent only the new one. Immediately I called IRCC and the agent told me he would request the authority to send it back. I raised a web form as well but I don't what should I do at this moment. Do they usually send through a different mail?
