@betterhavor. I think 2 days wont be a problem.
But I do not understand how you got your GC without having sent all the required documents? The passport copy is one of them. I thought it was taking a bit longer for me to get any kind of news from them because I sent my passport copy 10 days after my FI (I had to get a new one) but obviously it doesnt matter to have the file complete or not. I thought they were very strict about it. Very surprised and really dont know what to think anymore. It's been 3 weeks today since my FI. My status is still applied. Didnt get no grooming email, I dont even know if they know about me!
At least after 3 weeks I would expect my status to be "under review". Just that. A mark that they know about me. Very frustrating.
