Visas & permits

Entry visas are required by all nationalities, and are valid for one month.
Evidence of a previous visit to Israel or South Africa will result in a visa refusal.
Permits are required by visitors wishing to travel anywhere outside Khartoum, and can be difficult to obtain. Visitors arriving in any town or city in the Sudan must register with the police on their arrival, and show the necessary paperwork.
For those wishing to visit archaeological and/or historical sites, permits are again required. These are often fairly expensive, and can be obtained from the Department of Antiquities in Khartoum.
The Tourist Information Office in Khartoum will issue visitors with a photography permit. This is essential for anyone wishing to take photographs anywhere in the country, and is issued together with a list of items which may not be photographed. Having said this, it is probably better not to try and take photographs at all here, as permits are often ignored by those in authority, and cameras and film can be confiscated.
