Even after you have provided all the needed papers listed on the Embassy/Consulate/Visa Application Center's official website, the embassy may still ask you for more depending on your unique circumstances.
The length of a South Sudan visa is determined by how long the South Sudanese government issues the visa for. Once the applicant has their visa, they are free to enter the nation and remain there as long as the visa is valid.
Before visiting South Sudan, consider the following travel advice: Do not go on your own. Day or night, never go on a solo stroll. Have no faith in anyone (many scams can happen). Don't go to South Sudan to meet up with someone you met online. Avoid recording images or films of government structures, bridges, airports, or the military zone. Stay away from exposed areas like patios. Attending public events is not advised since terrorist attacks might occur at any time. Never carry anything of value with you. Don't store or utilise illicit substances. Don't consume anything that is offered to you, either. Avoid engaging in same-sex behaviours since they are forbidden.
Two months before to the date of trip is the earliest time to apply for a South Sudan visa. It is advised that all visa applications be filed ten days before departure in order to enable enough time for visa processing. Is the submission of my passport together with the application required? Yes, the Embassy will stamp the original passport with the visa. Therefore, the passport must have two vacant pages. Additionally, your passport must be valid for a minimum of six months after the desired stay.
