When planning a trip, always use this website to obtain the local,
direct-dial telephone numbers for the Customs/Border Protection facility
you intend to stop at. Additionally, I include alternates if weather
dictates a reroute at departure time.

On a return trip from Canada recently, I was thoroughly confused by
where to call, what time they were open, and when the service was
free. I never got a clear answer, but according to the AOPA directory,
Rochester has customs service 8:30am-5pm Monday through Friday.
Syracuse is the same, but there is a comment that after-hour service
must be requested during regular hours. The directory also mentions
overtime charges may be required after business hours.
