The Ambassador Extraordinary and Plenipotentiary of Ukraine to the United States of America is the ambassador of Ukraine to the United States. The ambassador is responsible for diplomatically representing and promoting Ukraine's interests in the U.S., with Ukrainian ambassadors having full authority to act on behalf of the Ukrainian government. Ambassadors are appointed and dismissed by the President of Ukraine, typically on the recommendation of the Minister of Foreign Affairs. If the ambassador has an absence from their position or if the position is left vacant, a Chargé d'Affaires ad interim, typically the deputy chief of mission, an attaché, or some other member of the embassy's diplomat staff, will be selected to fulfill the position's responsibilities in the intervening time until the ambassador returns or a new one is appointed. Since the start of the ambassadorship to the U.S., individuals holding the position have also typically been co-accredited as the head Ukrainian diplomat to multiple small neighboring countries as well as some international organizations such as the OAS. These concurrent responsibilities are assigned at the discretion of the Ukrainian president and agreement of the represented country/organization, in which the ambassador to the U.S. is authorized to represent Ukrainian interests in the additional countries/organizations as an ambassador-at-large, working remotely on a part-time basis from the Ukrainian embassy in Washington, D.C. Appointments to ambassador-at-large positions are generally carried out at some later point during the ambassador to the U.S.'s tenure.
