I did EWR on arrival there on a Saturday. I showed up 10 minutes early. The ladies working the "front desk," some kind of EWR contract security I think, didn't tell the CBP guys I was there until my appointment time came. Once they knew, they called me right in. Once I was in, the 5-6 minute video on how to use the kiosk and how not to bring apples in the country, some questions about travel patterns, a quick photo and fingerprinting and a discussion about the Dutch, and I was on my way. From application to getting my card in the mail was less than a week. Shockingly efficient.
