U.S. President Joe Biden plans to nominate Kristina A. Kvien to replace Lynne Tracy as U.S. Ambassador to Armenia.

Tracy’s tenure as ambassador to Armenia has expired. While all ambassadors serve at the president's pleasure and may be dismissed at any time, career diplomats usually serve tours of roughly three years before receiving a new assignment. 

Kvien, a career diplomat, had been serving as U.S. Ambassador to Ukraine. She's held various positions in U.S. diplomatic missions in Russia, France, the European Union and the Philippines. Kvien speaks Russian and French.
