On 5 April, US Secretary of State Marco Rubio declared the United States would immediately revoke visas for South Sudanese citizens following the northeast African country’s refusal to accept people deported from the United States. In addition, Washington plans to deny South Sudanese citizens at US ports of entry.
This move is hardly unprecedented, as the US has a well-documented history of using visa restrictions as a form of leverage, pressuring countries weakened by colonialism, neocolonialism and Balkanisation to conform to its political objectives. In doing so, it often punishes ordinary people.
