. . . the status is already Decision Made and they had just started to process it yesterday, April 13th
At the day I sent the application, I had accumulated around 800 days of physical presence in Canada within the past 5 years, so I am in compliance with Permanent Residency Obligations. The problem might have been because I did not send any supporting documentation, as they can check by themselves if I was or was not in Canada for the alleged period.
Any ideia? My application might have been summarily rejected?
As long as you actually have PR status the likelihood of the PR card application being "
summarily rejected" is near zero.
If, in particular, you were actually in Canada when you made the PR card application, and you are currently IN Canada, the odds are very good the Decision Made means the application has been approved and a new card will be issued. How and when it will be delivered can still vary (for example, it might be mailed within the coming days or few weeks, or it could be sent to a local office for an in-person pick-up).
A high percentage if not most PR card applications are approved upon being opened, and the vast majority are at least approved very soon after. While you were, as some of us say, "
cutting-it-close" (relatively), which can trigger non-routine processing that takes longer, for PRs perceived to be actually settled and living in Canada, and for whom IRCC has no reason to question or doubt they are in RO compliance, the process is simple: verify in GCMS the applicant is in fact a PR whose status has not been terminated or renounced, and is not subject to a Removal Order, and so long as there is no reason-to-question-presence, approve the application.
With very rare exceptions (and the only ones I have seen in the IAD decisions involve PRs who are NOT IN Canada) PR card applications are NOT "
rejected" because the PR is in breach of the PR Residency Obligation (notwithstanding how common statements suggesting otherwise here are -- comments here like "if PR applies without being in RO compliance the PR card application can be rejected" are overgeneralizing the procedure, as that is not how it works).
Rather there is a procedure for conducting a formal RO compliance examination which can result in the preparation of an inadmissibility Report, and if upon review that Report is upheld, issue a Removal Order. That is one type of non-routine processing. (Note: that procedure requires IRCC to consider H&C reasons, so at worst the affected PR will be given an opportunity to submit additional information before such a Report can result in the issuance of a Removal Order).
In Other Words: Looks Like CONGRATULATIONS Are In Order.
