I've a few questions I was hoping the knowledgable folk of Flyertalk could help with.

I've recently been approved for GE having completed Enrollment On Arrival at ORD. We have just received notification that my partner and child have been provisionally approved so on our next trip to the US later in the summer, I'm hoping to have them complete their in person interview.

Our arrival airport is SEA so that would be where they would do EOA. On the CBP website it doesn't state opening hours for the EOA office, just that it's available "during international arrivals". Our flight from LHR is scheduled to arrive at 18:00 and while not the last international arrival of the day at SEA, I'm aware this is potentially getting towards the end of the working day for the EOA office/booth. Is anyone aware of the actual time EOA is available until at SEA or have recent experience of accessing it after 18:00?

I'm keeping close eye on appointment availability for the SEA Enrolment Centre. Unfortunately at the moment there's no availability for the period will be in Seattle, however I'm aware this can change. The other option for completing the in person interview would be in Vancouver as we're visiting there as part of this trip to the US and Canada. YVR is listed on the CBP website as an Enrollment Centre however when attempting to book an in person interview it's not listed at all. YVR is also listed as an option for EOA for passengers traveling from YVR to the US. While we won't be departing from YVR for any part of this trip, is anyone aware if the Global Entry Enrollment Centre is before or after security at YVR? The CBP website states EOA is done at US departures. My thinking is if it's before security then my partner and child could potentially complete their GE enrolment interview at YVR if we swing by one day while in Vancouver.
