After an internationally recognized referendum on self-determination, South Sudan became independent on 9 July 2011 by the end of Africa’s one of the longest civil wars. Afterwards, South Sudan entered its civil war on December 15, 2013. It happened between the two governing bodies of South Sudan President Salva Kiir and Vice President Riek Machar. The African Union, the United Nations, the United States, and the other Western forces had made major diplomatic attempts to bring the war to an end but failed. In response to this civil war, mass people of South Sudan have started to take refuge in the neighbouring states. More than 1.6 million people have been internally displaced, with approximately 200,000 finding shelter at UN PoC sites in front of UN bases. They fall under troublesome situations in the receiving countries as well. Though the United States along with other international organizations have significant political, financial, and military investments in the refugee receiving countries by the war in South Sudan, such as Ethiopia, Uganda, and Kenya, local integration is not still welcomed by them. Though this paper has some limitation like its only qualitative based research so there is lack of resources for explaining overall situation. In spite of some limitation the study will try to evaluate the impacts of the South Sudanese Refugee Crisis on the neighbouring states through local integration with the secondary data collected from different books, journals, newspapers, articles, etc. By following the qualitative research approach. Basically this paper has two purpose. Firstly it explains the historical background of conflict. Secondly it describes the impact on neighbouring states in various event of life. In conclusion, finally, some policies will be recommended which have present implication to solve the conflict and ensure the proper treatment of refugee who take shelter in different neighbouring states.
