hola
verdad que tu necessitas visa B y puedes obtenerlo en ambajada US en Madrid o Trinidad o Barbados o de otra manera (entrada en 2019) => lee esto :

(1) Obtain an E Visa (see note below) by applying on-line well in advance of travel.
(2) Take a ferry or plane return trip to a convenient USA destination (it is easy to go to the USVIs from the BVIs).
(3) Expect for each person to be finger-printed and photographed at the USA Immigration desk on arrival. Then you will have a date-stamped visa entered into your passport. This is multiple entry within the 90 day period.
(4) Return to your yacht and re-enter USA waters when desired, phoning in advance to notify your arrival (use either the Toll Free Number 1-877-529-6940 or (for Puerto Rico) (787) 729 6840.
(5) Expect that you will be told to remain on board until you are advised it is OK to land. (We received a return phone call 30 mins after our phone notification of arrival, and were then told we could go to Customs at the airport in Culebra).
(6) Obtain your yacht's cruising licence from Customs; this will be valid for 1 year.
(7) Expect to pay arrival costs which vary according to LOA; expect to pay between $20-40. No charge in St Thomas as it is a free port.
(7) Phone on arrival at subsequent changes of area; i.e. you should notify Vieques if you are going there after Culebra, then Ponce etc. Customs will provide the correct phone numbers to use (or use the national toll free number above). Note you do NOT have to make a personal visit to Customs or Immigration as you cruise until such time as you are leaving USA waters. The phone notification is sufficient unless advised otherwise.
(8) Obtain clearance in the usual way before departing USA waters; note that many countries (including Panama) are now very fussy about a boat having proper clearance papers.
(9) Note that your passport will not be stamped again, regardless of how many times you enter or re-enter USA territory within the 90 visa period.
(10) The De-Cal program is not applicable to private, non -USA registered boats, although we inadvertently bought one on-line!
(11) We were asked by the very helpful officials in St Thomas to refer Noonsite readers to the publication 'Carrier Information Guide, US Documentary Requirements for travel). It does not have more than the bare bones of the acceptable process though.
