Inspired by recent posts here I put in my Global Entry renewal application using the newer TTP trusted traveler system since the previous GOES has been replaced on the morning of the 20th - the Homeland Security website says the grace period is now 24 months instead of 18 months because of their backlog.
I got a notification message at 1:10 am on the 22nd that my renewal has been approved, no in-person interview necessary. That's less than 48 hours turnaround, not 24 months!
There is a list of in-person enrollment centers for new applicants and another list of enrollment centers that allow you to enroll on re-entry from your next int'l arrival -- it's curious that SFO is the only place listed on the first list, but OAK and SJC and Sacramento are listed on the second list.
The new expiration date is 5 years from my next birthday; If I had waited until the day before my birthday to put in the renewal and the turnaround had been 24 months, then maybe I would have gotten two extra years coverage for free?
(I'm not disappointed, just spitballin')
