My husband's work history didn't get us any points (non-Canadian), but we put it in 'Work History' so he had to get letters anyway. One of the letters came back and he had apparently had the dates of employment completely wrong. Off by about 6 months. Can I just explain that in the LOE and change it on the PR application and have it be okay? Since we didn't get points for it anyway nothing really changes, but I know you aren't supposed to change work history after getting an ITA. Will it be a problem?
