Read the whole thing. Here is the piece, especially in bold, that is not clear.
Travel –
Facilitating authorized travel and commerce, increasing contact between Americans and Cubans, and supporting civil society in Cuba:
Transportation by vessel of authorized travelers – between the United States and Cuba only and without stops in third countries – will be authorized by general license. Certain related lodging services aboard vessels used for such travel will also be authorized.
License Exception Aircraft, Vessels, and Spacecraft (AVS) will authorize temporary sojourns to Cuba of certain categories of vessels. Eligible categories of vessels are cargo vessels for hire for use in the transportation of items; passenger vessels for hire for use in the transportation of passengers and/or items;
and recreational vessels that are used in connection with travel authorized by the Treasury.
License Exception AVS will authorize aircraft on temporary sojourn to remain in Cuba for up to 7 consecutive days and authorizes vessels on temporary sojourn to remain in Cuba for up to 14 consecutive days.
Close relatives will be allowed to visit or accompany authorized travelers for certain additional activities. In the January changes, OFAC permitted close relatives to join visits related to official government business and certain educational activities, and to visit additional family members residing in Cuba. Close relatives now also will be allowed to visit or accompany authorized travelers for additional educational activities, journalistic activity, professional research, and religious activities, as well as activities related to humanitarian projects and activities of private foundations or certain research or educational institutes. For purposes of this provision, a close relative is defined as someone related to a person by blood, marriage, or adoption – and who is no more than three generations removed from that person or a common ancestor with that person.
All authorized travelers will be allowed to open and maintain bank accounts in Cuba in order to access funds for authorized transactions while in Cuba.
