Applied 11 Sep 2013
Conditionally approved 15 Oct 2013
Interviewed at Champlain, NY 18 Oct 2013
Card received 25 Oct 2013.
So that went about as smoothly as I could have hoped. Apparently Champlain isn't too busy (alas, it's about a 3 hour drive from here). They told me that if you showed up randomly as a walk-in, there was about a 50% chance they could process you that day, since they often get gaps in the interview schedule. Interview took 10 minutes. Crossing the border to Canada to get my iris scan and back took another hour (mostly getting back into US, that Nexus card can't show up soon enough...

)
