Are you based in the USA, such as on a work visa? That's different as you have a local address. I wonder if non US residents will be, in any way, to get a card, even if it's just for those who can provide a US mailing address. I've written to cbp in this regard, I'll probably get a cookie cutter response but hope to get it on their radar that the card has its uses - - you can use the global entry / nexus vehicle lanes while entering Canada, and entering the trusted traveler security lanes at Canadian airports requires one of a few types of cards, such as nexus or global entry. Hope everyone else sends similar messages so they get the idea that sending the card to non US residents would be beneficial.
