Registering for ROAM for the USCG vessel is straightforward. You also need to add travelers in the app. The app has the eligibility requirements in more succinct detail than the CBP web page - "US citizens, nationals, and lawful permanent residents; Canadian citizens, permanent residents who are nationals of a Visa Waiver Program country"

We've used ROAM more than a dozen times and it was pretty smooth. Sometimes the approval comes through right away. Sometimes they want a video call and see each person with their passport. One time it was a day trip and our guests had already headed home and it was not a problem. I wish the BVIs had the equivalent, but I do not expect that to happen.

We've had the ROAM program manager out for SSCA events in Baltimore. The CBP wants us to use ROAM to reduce workload. No more walking to the airport on Culebra, I hope.
