"Divorce before landing but after COPR".
I am the Primary applicant in Express Entry (Skilled Worker) and my wife and child are secondary applicants. We were granted COPR and PR visa but we have Not landed yet.
If there is a divorce before landing what happens to Secondary applicants (My wife and Child)?
Will they still be able to land and get their PR status? Also, should I inform IRCC?
Finally, will this affect my application or my COPR and PR visa as a primary applicant?
Thank you and hope I can get help on this matter.
