US President Biden is set to nominate Indian-American career diplomat Gautam Rana as the new US Ambassador Extraordinary and Plenipotentiary to Slovakia, the White House said in a statement last month.

Biden nominated Indian-American diplomat Rachna Sachdeva Korhonen as his envoy to Mali in April, the third such nomination of an Indian-American in over a month.

In March, President Biden nominated two Indian-Americans as US envoys. He nominated diplomat Puneet Talwar as the country's ambassador to Morocco and political activist Shefali Razdan Duggal as his envoy to the Netherlands.
