Without proof they are anecdotal. Without proof that the hold was because they were not in Canada, they are anecdotal.
Once you provide source material from the IRCC instruction manual, stop giving people misleading advice. You are quite literally telling people to misrepresent when the instructions are clearly to let ITCC know that they are outside the country for longer than two weeks. If their applications would be denied due to it, and banned from applying for citizenship for the next 5 years, you walk away scot free.
That's why I said need to estimate the when will receive the next steps. Based on other people's cases, if you think you won't get any update within the time you are not in Canada, or you can get back to Canada if you receive any update, it's okay to not report to IRCC.
IRCC would never explain why the cases are in hold. I am waiting for 17+ months and lots of people waiting since 2021, IRCC just didn't assign any officer to their cases or way over due. At least I can see it from my GSMC notes.
I just provide advice to people to avoid get into this case when No officer got assigned to the application.
Maybe if you are 2023 applicant, you are fine. IRCC launched a pilot program this year, that's why you can see 2023 applicants get their oath within 4-5 months. They are hiring new employers working on pilot program.
But for 2021 and 2022 applicants, some cases even the waiting time are longer than 21 months, the IRCC agent still say those cases are routine, and wait for IRCC officer to review. So they are shortage for 2021 and 2022 applicants (in old system) but lots of officers on 2023 applicants (new pilot program)
I didn't say not to report leaving, just need to decide based on personal situation. I just don't want people get stuck in their applications. You can suggest people always report, then if their application was put on hold or no officer look at it even after the hold, you also walk away scot free. It may take years to get application approve.
