Context: I am a Canadian PR living in Canada (not a North American citizen). I had applied for and received NEXUS membership when I was in the US and had a valid US visa. I satisfied the eligibility requirement then since I met the 3 year residency requirement (in US) and I was a Canadian PR at the time.
Now my US visa expired and I have moved to Canada since, I no longer visit US and have never got a chance to use my NEXUS card for entry for one reason or another. Note that there's no way to update visa information on the Trusted Traveler Program website.
Note the NEXUS eligibility criteria here: https://travel.gc.ca/travelling/documents/nexus and https://www.cbsa-asfc.gc.ca/prog/nexus/application-demande-eng.html
Based on this am I right to think that I still remain eligible to possess the NEXUS card? Neither of those links explicitly state that changes in visa status of one country (either US or Canada) makes me ineligible (of course, as long as I am a citizen or PR of the other country which I am)
Assuming that I am still eligible for the NEXUS membership, this brings me to my next question. If I receive a US visa, e.g. a tourist visa, am I required to report to a NEXUS enrollment center in Canada (or US), either separately, or when I am traveling there? Getting a US visa still hasn't negatively affected my eligibility.
And lastly, in my current situation (Canadian PR, no US visa, valid NEXUS card), can I use NEXUS card processing if I am entering Canada (or any other country that accepts NEXUS cards on their kiosks), for a faster entry?
