I think a lot of Haitians live along the south sides, starting on the east end of the island.
They even have Haitian Creole radio stations running for these newcomers. Haitians constitute a large, large number of Cubans now.
There are Americans who started looking into the idea of moving to Cuba for their retirement and they were informed by the US government that they would never been allowed to get their Social Security checks which would begin at 65 years of age, sent to them there. The US government already had that idea covered.
Also, when the US government learned that one of the former Cuban "exile" paramilitaries moved to Cuba to start his own political group, "El Cambio Cubana" it started threatening to retrieve him from Cuba and put him in prison.
Meanwhile, Cuban-Americans slip back and forth to Cuba daily.
Cuban American politicians hate it so much that some Cubans do that they have tried to have the US taxpayer-supported benefits to Cuban Americans suspended if they learn they have visited Cuba, trying to force them out of making those trips, and making the propagandists look bad. Senator David Rivera was one of them. Filthy people, trying to control Cubans over here just as their predecessors did in Cuba, before the Revolution.
Everywhere there are right-wingers only monsters flourish.
