my friend just recently upgraded from PR to Canadian Citizen
after he went to Nexus office to update his info - he was told to log in and click replace card

we were wondering since his Nexus will expire next year in April-2024
is it better to just apply for renewal and just pay $50
if he does apply for renewal now, and let's say it gets approved next month - when is the expiration?

side question - does he need to apply for renewal now or even card replacement if his info already got updated from the Nexus office?
wouldn't the border officer see a updated info?
