Greetings and welcome aboard the CF, Carrtay.
The master of a pleasure boat must report to U.S. Customs
and Border Protection (CBP) immediately upon arriving into the United States from a foreign port or place and must provide a formal vessel entry on CF 1300 within 48 hours.
Cruising licenses exempt pleasure boats of certain countries (ie: Canada) from having to undergo formal entry and clearance procedures and can be obtained from the CBP Port Director at the first port of arrival in the United States.
There are four exceptions to the face-to-face inspection
at a designated reporting location, NEXUS, Canadian Border Boat Landing Permit
(I-68), Outlying Area Reporting Stations (OARS), and the Small Vessel Reporting System (SVRS). Participation in any of the programs does not preclude the requirement for physical report upon request by U.S. Customs
and Border Protection.
