The CBP Office is located near FlightStar
A request for CBP clearance must be made in advance by speaking with the Duty Officer. An APIS transmission or voicemail will not suffice. Arrangements for flights intending to arrive outside of the posted hours must be made by 5:00 PM on the prior business day. This includes weekends and holidays. The officer is responsible for many duties which take him/her away from the office. It is advisable to call in advance to insure that the officer will be available.
