Except for Swiss and Israeli nationals, everyone will need a visa.
Visas may be single or multiple entry, although multiple entrance is preferable over single entry. Multiple entrance visas are typically valid for a year, while single entry visas are valid for three months. They are $150 and take two days to complete. If you come from a nation that does not have a CAR embassy (for example, New Zealand), you may apply for a CAR visa at a French consulate/embassy. It is unknown if other nationalities (residents of the United States, France, and so on) may apply at a French consulate. The rules for getting a visa differ across CAR embassies and from month to month. You may apply for a CAR visa at the country’s embassies in Yaounde, N’Djamena, Brazzaville, Kinshasa, and Khartoum. The Central African Republic also maintains embassies in Washington, Paris, and Bonn.
Border crossings with Chad, Sudan, South Sudan, and the Democratic Republic of the Congo (at least east of Bangui) are very dangerous, and any effort to cross them by land is discouraged. There are no land connections between the Central African Republic with Congo-Brazzaville (Republic of the Congo).
