I don't think so. But NB will send you an email letter after a month of your landing - they woul'd like to know your address and other details about job etc.Thank you for your reply...
Would NBPNP tell us to move to Canada in the first or second year? Like, would they tell us, come now or you lose your status? Due to some personal reasons, we may need extra time before we make the move....
So you can explain your circumstances replying to that letter.
