Do I require to submit passport details of my wife and children for?
When you submit the EE form it will not ask you for those details, but yes eventually since they would be accompanying you and are applying for the same PR status for all of them, you have to provide their passort details. There will a separate page that will ask for national ID where u can even provide PAN or voter ID or anything. But at the end of the form , in upload page, you will be asked to upload all their passport copies.
