One data point, and one question... Data point: I applied online on June 4, got the conditional approval notification today (June 28) so that's just more than a 3wk turnaround. I travel intl maybe 6-10x per year if that matters.

Question: is the interview the final step before you can use the system? Specifically: if I schedule the interview for the outbound leg of a two-day trip to europe, will I be able to use the system on my return? Or are there more steps after the interview that I need to be aware of?
