Ditto about SFO. Was taken to Feb 2018 page. Nothing at west cost airports earlier this week when I was checking (SAN, LAX, PDX and SEA). Just so happened work trip came up that had me visiting DFW. Snagged a date and make the trip fit my new schedule.
Now there's an option to have your interview when entering the country! This may be the route wife will have to go. No chance of doing a walk-in and wait at SFO before we depart for Europe in four weeks.
