contact the CBP port to re-secure permission to land.

until CBP advises otherwise. A CBP officer will meet the aircraft.
• All crew and passengers must make passport, VISA, medical, aircraft registration available for
inspection.
• Be prepared for all passengers and crew regardless of citizenship to disembark the aircraft for
processing and inspection inside the CBP FIS.
