All foreign nationals wishing to enter Sudan must obtain a visa in advance. The cost of a Sudan visa varies depending on the applicant's nationality and the type of visa required.

A single-entry visa for Sudan costs US$170 for US citizens, while UK citizens pay £120 (about US$155). Canadians must pay C$250 (US$190), while Australians are charged AU$295 (US$215). New Zealanders pay NZ$265 (US$175), and South Africans R3290 (US$225). Other nationalities must inquire with their nearest Sudanese embassy or consulate for pricing information.

Visas are valid for stays of up to 90 days, and can be extended once within Sudan for an additional fee. Those wishing to stay longer than 90 days or who require multiple entry visas must apply for a different type of visa.
