I did my interview on a walk-in - 7 years ago. They don't do walk-ins anymore, and everyone needs to have an appointment (I know of a couple that needed 2 appointments but there was only available one - so CBP told them to book another appointment for later in the day). I just called JFK CBP office and they confirmed no walk-ins
I went as a walk in today in JFK (appointment was for 10/2)
The officer told me with pleasure but you will wait after all appointments, and as my luck their were 6 people before me, so wait time of 35min and done. Bh.
Even took the pic of the signs on the wall
