NEXUS sent me e-mail saying I've been approved for the program and have to schedule an appointment at the airport to be interviewed, fingerprinted and photographed, and have my retinas photographed, too. They have a very simple online booking interface, showing the availability and allowing me to schedule, move and cancel appointments.
Nothing is available this month.
Nothing is available next month.
There are availabilities the following month, but I'm scheduled to be away working for the whole month,
Nothing is available the month after that.
Nothing is available for the two following months.
I kind of suspect that they have only opened the booking system for appointments in the next three months. I could wait and see if more opportunities opened up, but the e-mail states that I must book within 30 days.
I'll looked at some other centres and saw much better availability, so I'll wait until I know my work assignments and try to arrange an appointment there and then. I'm still kind of freaked about subjecting myself to US registration, though. I picture my fingerprints being in the same big database with all the convicted criminals, getting checked against the fingerprints on murder weapons. Also I hate getting my eyes examined at the optometrist, so the retinal photograph is going to be freaky.
