I'm planning to do the same as they are not following their own rules regarding our case.I am 2019 OINP applicant AR:July 2019. Single applicant, inland, no dependent. I learned through my GCMS notes that my case was approved November, 2020. I have been DM for over half a year!!! my case has been held in CIO for over half a year after its approval!Still No copr no portal until today! The whole process has already taken two years. I called, sent webforms, requested gcms notes and contacted MP for over ONE HUNDRED times in total. None of the above methods helps. I am planing to make mandamus. Anyone had experience with mandamus here? Any successful cases after mandamus? I contacted some lawyers. One of them said it may not help even my case is in such a bad situation.
Let me know how it works out for you.
