Do France passport holders need a visa to visit SS?

Yes, French citizens need a visa. The most practical route is the official South Sudan eVisa, which must be obtained online before travel; there is no visa-free or standard visa-on-arrival channel for ordinary French passport holders. A France ordinary passport holder traveling to South Sudan for tourism or a short visit requires a visa. South Sudan operates an electronic visa (eVisa) system available to citizens of all countries, including France, applied for through the official portal at evisa.gov.ss. France is not on South Sudan's short visa-exemption list (which covers only Egypt, Kenya, Tanzania and Uganda) nor on its ordinary-passport visa-on-arrival list (Burundi and Rwanda only; VOA otherwise applies to diplomatic/official/service/special passports). French travelers must therefore apply for the eVisa online and receive an approved PDF before departure. The single-entry eVisa is typically USD 100, with multiple-entry options at higher rates, and the eVisa is generally valid for 90 days from issue. Processing is usually 3 to 5 business days (72 hours in many cases), with expedited options available. A yellow fever vaccination certificate and a passport valid at least six months are standard requirements. Travelers should also note that South Sudan is subject to significant security and travel advisories; this guidance covers entry documentation only.
