cruise to Cuba help
We're a US documented boat & US citizens. We're planning a trip from west coast Mexico (Chiapas where the boat's been for over 1 year) through the canal to Colombia before sailing north to Jamaica and then south coast Cuba before heading to Mexico (Isla Mujeres). Question is what, if any formalities, regards US authorities (CBP?) are we required to partake in for entering Cuba? Since we're not leaving from the US to get to Cuba and not returning to the US after Cuba we're thinking nothing is required but unsure.
Any help will be appreciated!!
