There was a question regarding the legal status of the WT, here is some information on that:
3. (C) The religious leaders explained that the Jehovah Witnesses have rapidly expanded since 1994. They stated that in 1996 there were 70,000 practitioners in Cuba, and that since then the number has grown to 90,000. The number is far greater than is cited in several studies of religion in Cuba. There has been a steady increase despite the fact that the community has lost many members through emigration. Jehovah Witnesses are frequently approved to travel to the US as refugees. The organization has not petitioned the government to be officially recognized as a religion. They are not a member of the state sanctioned Council of Churches. Because of doctrinal differences the organization does not get involved in ecumenical efforts. The leaders presented that they have a minimum amount of friction with the government. The members steer clear of any involvement in politics. They are not allowed to establish individual "Kingdom Halls" as places of worship. They said that their members hold regular meetings and bible study classes without difficulty in private homes throughout the island. Some of these residences can accommodate several hundred people. The leaders said that even without having official status as a legal gathering, the local authorities have given verbal permission to hold the meetings. The leaders indicated that they are very respectful of their neighbors and the meetings have not been the subject of complaints.
