NEXUS card after naturalization

Hello,

I will be taking the oath of US citizenship on Sept 23. I'm wondering whether after Sept 23 I will continue to be able to use my NEXUS card (for travel between the US and Canada) and, if so, under what conditions:

1. One scenario would be that, since the NEXUS card is a WHTI compliant document, I would only need to update my NEXUS card with the details of my naturalization certificate and then I should be good to go.

2. A second scenario would be that I will require a US passport but then can update my NEXUS card with the new passport details and then I should be good to go.

3. But a third scenario would be that I'll need a completely new NEXUS card because on the front of my NEXUS card I'm identified as a Canadian citizen--and I need US citizen documents after getting my citizenship.

Which, if any, of these scenarios is closest to the truth?

I asked our NEXUS guy and he says that you need to contact the NEXUS Office to get a new card that shows you are a US Citizen. You would likely only get a warning if encountered without the new card as you are not doing anything wrong.

Thank you for the reply, laws.
