In our case, it took so long that I asked our Congressman, Mark Souder, for help. On a street in Havanna. Generally speaking, we found the Cuban people to be very open and friendly to us. Since tourism is a large source of revenue, the Cuban people go out of their way to make foreigners feel safe and welcome. There is a policeman on almost every corner.
Many tourists come from Europe, Mexico, Central America, and Canada.
However, few people come from the United States, because of the blockade which has been in force since Fidel Castro's communist forces took over the country in 1959. Havana is a very nice city, modern in many ways. However, we could see the lack of repair to infrastructure, houses, and buildings. Cuba remains a communist, socialized state. If you run a grocery store or restaurant, your profits go back to the government.
