The Trump administration has added seven countries, including five in Africa, to the list of nations whose passport holders are required to post bonds of up to $15,000 to apply to enter the United States. Thirteen countries, all but two of them in Africa, are now on the list, which makes the process of obtaining a U.S. visa unaffordable for many. The State Department last week quietly added Bhutan, Botswana, the Central African Republic, Guinea, Guinea-Bissau, Namibia, and Turkmenistan to the list.
