The primary applicant is currently in Canada and has been waiting for the virtual landing since January 15, 2024. The dependent, on the other hand, is outside of Canada and received the Confirmation of Permanent Residence (COPR) on February 15, 2024, with the deadline to enter Canada being June 4, 2024. However, the dependent is unable to enter Canada until after the primary applicant's virtual landing. If the dependent's COPR expires before the primary applicant's virtual landing, and IRCC is unresponsive to queries, what should be the next step for the dependent or whom should they contact in this situation?
