As you know, you must test to return thru the USVI or PR. The requirements are slightly different but if you are vaccinated they will allow a rapid antigen tests. Those are available in the BVI at several clinics. Alternatively, they also allow a home rapid antigen test but it must be the type that is proctored by a telemedical service. There may be others but the only one I am aware of is available at eMed.com. You can bring those with you and use that test for your entry back into the USVI or PR.

Odds are very good that this information will be outdated by the time you travel. Check back a week or 2 before you travel. Your best information is going to be on the USVI Travel Portal
