So your posts are confusing as you say your wife was primary applicant so were you and your children not included as accompanying your wife for PR ?
In another post you implied you had PPR request for FSW program.
Your wife as primary applicant obviously either has to land either first or at same time as any dependants with their COPRs. If the primary applicant lands first then the dependants can land separately later with their own COPRs
Or are you as dependants just planning to travel as visitors in which case you would all need TRVs to travel as immediate family members once your wife has landed as a PR.
everyone is included and everyone has the PR Visa and COPR issued in November 2020. however . the issue is traveling ..my wife's(Primary applicant) sister is there thus my wife can apply for the extended family option to get the authorization letter...
The understanding I got from the above discussions is that only she can travel and once she is there we can travel as her immediate family.
Having young kids its difficult for us that she travels first (without the kids) and then after her getting the PR card we can travel .. so my question was do we have to wait for her to physically get the PR card(which can take a month) or can travel as soon as her landing is done ..hope this clears the confusion
