Hello all.
As of 3:15pm, I've became a landed immigrant of Canada!
The process was pretty painless. It took all of ten minutes to finalize my landing. But it took another twenty minutes afterwards for them to go through all my B4As, making sure everything is all in order. My wife and father-in-law was with me throughout the process, and was happy to see me get through it all in one piece.
They took my COPR, stapled part 3 of the COPR to my passport, stamped it, wrote some numbers in it, explained to me my rights and responsibilities as a permanent resident, and told me I was all set. I had to get a hold of someone else for the B4As, where they copied them, and gave me back the copies, but not before
they stamped them all, wrote a file number on all of them, and had me sign the B4 that I forgot to sign. The stuff I already brought over got marked off, too. People there were quite friendly and helpful.
Congrats!
Anyway, I wish you all good luck. I'm sure I'll be lurking around for a while here, but now I'm off to my new life!
