I've seen another case where a guy had his application returned because the reference letters were not matching the NOC. His letter was completely different from mine.
If I hadn't reached the minimum points, they would've told me, but in this case, they've text-marked the missing form on the checklist (5406 - principal applicant + your spouse) and put a post-it to call my
attention to it. I also received a letter (Appendix C) with a checklist of that appendix and with the spouse's form 5406 marked as missing.
Then there's this other letter, which is kinda generic, with the Work Experience text-marked, saying I need to match the requirements of 1 year experience. They did not text-mark that on the main checklist, only there. After I received my application back, I wrote my own job duties reference letter and asked my manager to sign it. Also wrote a letter stating the reasons why I did that and couldn't give them what they need like they need due to company policy. Can't do anything other than that to prove it.
The attempt #2 has been dispatched already...
Thanks for the advice.
