In which African country did the US suspend visa processing?

The decision to suspend visa processing in Zimbabwe was primarily influenced by ongoing issues related to governance and the political climate within the country. The U.S. government has raised concerns over human rights violations and the lack of transparent democratic processes. This action reflects a broader strategy aimed at encouraging reforms and holding the Zimbabwean government accountable for its practices.

In this context, the suspension serves as a significant diplomatic tool, signaling that the U.S. is monitoring the situation in Zimbabwe and is willing to take steps that impact potential travelers and the nation's economy as a means of advocating for necessary changes. The other countries listed have not faced similar visa processing suspensions as a result of the same issues, which helps to clarify why Zimbabwe is the only correct choice in this instance.
