Was looking on the GE Location list today to see if NAS was added since I'm flying out of there today. Looks like the list has been updated and pretty much every major port of entry in the US has been included.
NAS has four kiosks on the left hand side; officer said they just got them a few weeks ago. Very nice improvement to have an updated list and seeing most of the Caribbean pre-clear stations having it now.
