We got ITA on May 4th. My wife didn't include my kids by my previous marriage on the profile, so I want to decline the ITA and make a new profile, but my wife wants to submit the application with a letter of explanation. She wants to say this was an honest misunderstanding, because she didn't think my kids were part of her family, as they don't live with us and they are not coming to Canada. Also on the profile form it doesn't clearly state spouses kids should be included. What do the experts things, would CIC accept this was an honest misunderstanding or would it misrepresentation?
