Americans visiting Cuba
On the 17th of December 2014 the Obama administration decided something historical: Americans can Travel to Cuba. Well actually Americans can travel if the trip falls under one of 12 categories.
Starting September 2016 there are commercial flights between various US and Cuban cities. This makes it possible for American citizens to book flights over the internet as easy as to any other part of the world. You basically just needed a valid passport and off you go.
Neverthless in July 2017 the Trump administration reinforced the travel ban for US citizens to Cuba, making it only possible to visit Cuba as part of an official group tour.
So the US embargo is still in place and for this reason Cubafortravel as an official agency is NOT organizing travel for US citizens to Cuba.
