CBP ROAM description

The official CBP ROAM App (formerly OARS) from U.S. Customs and Border Protection allows pleasure boaters and other eligible travelers who arrive at remote locations to report their arrival online. In addition to submitting a report of arrival, pleasure boaters who are not currently enrolled in a Trusted Traveler Program, Local Boater Option, or I-68 program who are currently required to report in person may be eligible for a video inspection.
Disclaimer: This is a pilot version only for use in limited areas. Contact your local Port of Entry for guidance.
Create a trip by adding travelers, your mode of travel, your location, and contact information.
After you submit a trip, you may receive a push notification on your device to start a video chat with a CBP Officer to finish reporting your entry into the United States.

Note: In order to use this application, the Android device’s operating system needs to be Android 4.4 (KitKat) or above
