If you are a Canadian then ABTC requires CBSA approval; nothing weird about that. You can't delegate an approval decision to the government agency of a foreign country. If you are US citizen, then CBSA is not involved in ABTC and this could just be a technical system limitation.
You'd think so, and that's what I thought after I naturalized. But I was able to update my citizenship information at a local Global Entry enrollment center by walking in. This is what's confusing to me. I first thought Nexus is a separate program and Nexus members just happen to have the privilege to use GE kiosks. But apparently GE enrollment center officers *can* update Nexus member's citizenship information.
Then I thought they must be able to do APEC cards, since that seems to be a solely American "thing" compared to updating your citizenship which presumably concerns both the American and Canadian authorities. If you can do the latter at a Global Entry enrollment center, but you surely should be able to do the former there...
To be clear, I'm an American, which is why I said it's weird to need CBSA approval for the APEC card, when CBP alone can update my citizenship information. What the officer said first about only the CBPs at the borders and pre-clearence facilities having access to Nexus membership database would have made sense, if not for the fact that CBPs in NYC can update a Nexus member's citizenship.
