I wasn't able to find anyone with a similar issue so I thought I'd start a new thread. I did my IME upfront for my PGWP and I have since renewed my passport, which means the passport info I have on the IME sheet is no longer valid (number, issue and expiry date). I did write a letter of explanation. Should I merge that letter together with my IME sheet into one pdf file when submitting? Or should I just upload it under optional documents. I'm worried that they won't pay much attention to the optional document and if I have it together with my IME sheet it might be clearer. But I'm not sure if that's allowed.
