Ahhhhh yes I did misunderstand. I thought you said that you landed with a scanned COPR which just seemed insane to me, lol, but as proof of having already landed, that's different. I suspect it's probably a case-by-case basis, some airlines or agents might be fine with a scan, others might require the paper copy. Apologies for the misunderstanding!
I would have expected you to have heard by now, try dropping a case-specific email.
Applying for and working on an IEC doesn't impact the spousal application at all, so you can go right ahead with it.
