Restrictions on travel to Cuba have been a key and often contentious component in U.S. efforts to isolate the communist government of Fidel Castro for much of the past 40 years. Under the Bush Administration, enforcement of U.S. restrictions on Cuba travel has increased, and restrictions on travel and on private remittances to Cuba have been tightened. Several legislative initiatives have been introduced in the 109th Congress that would ease restrictions on travel and remittances to Cuba. These bills would, among other things, lift overall restrictions on travel to Cuba, lift the overall embargo, and ease restrictions on exporting agricultural commodities to Cuba.
