Both of the interview locations in Washington state do not have the iris scanners needed to take your photo so we can use our Nexus cards at Canadian airports. My wife and I scheduled our interviews in Vancouver at the end of December; only one slot was available in Toronto or Fort Erie during the time of our visit in early September. Slightly annoyed at having to wait so long for the interview; on the other hand, the flights to and from Vancouver will get me to 1K on United this year. :-)
