We started using ROAM late last season at CYOA. We have US customs decals on all of our boats. The first step is to make sure you have the US Customs decal. It works well both returning from BVI's or in your case arriving in Puerto Rico. You will want to check in with your charter company about the decal well in advance. With the decal and ROAM app you should be able to clear in both places, St John and Culebra via the app. Without it Puerto Rico/US Customs now requires you to present in person. This means going into St John to clear into the USVI then going to the Airport in Culebra and clearing in. They will not clear you over the phone as before. The options are conform with ROAM or present and be inspected. If it is your own boat then register it yourself with US Customs and get the decal in advance.

PS next time rent from us at CYOA easier access to St John and the Spanish Virgins.
