Freedom of movement
Freedom of movement within the country, foreign travel, emigration, and repatriation are guaranteed by the Constitution, but the first two are restricted in practice, with officials demanding bribes at checkpoints. Extortion at illegal road barriers discourage commerce and travel, thus seriously crippling the nation's economy. Freedom of movement is also difficult in conflict zones. Foreigners, other than diplomats, must obtain exit visas in order to leave the country, and this may necessitate proving that they do not owe money to the government.
