Or
If I forgot to add one holiday days in physical presence form
Or
Any error in form example, mistake or forgot to write information
Will it lead to refused citizenship application
Your reply will be greatly helpful
Much of this has been discussed in other posts on this forum recently.
For example, in
https://www.canadavisa.com/canada-immigration-discussion-board/threads/us-citizen-canadian-pr-applying-for-canadian-citizenship.546488/#post-6763418.
Remember that it is up to the citizenship officers to determine if you made a small error that they can fix in their files and thus overlook, or if you made errors that make them worry about the veracity of your application, or if you made errors that appear to be intentional misrepresentations. The outcome is going to be very different in each of those cases -- and it is their policies and professional judgement that will inform their interpretation of what happened.
So, a typo or something minor you forgot may not cause any difficulty at all. It may cause your file to undergo extra scrutiny, and you may end up having to prove (by gathering and sending much more information) your case. Many errors in your file make that almost a certainty. And errors that seem attempts at misleading them (or actual attempts at misleading them) may cause your application to be denied.
So, be as accurate as possible. And if you notice you forgot something, or were unclear, send IIRC a clarification.
