Who is the Ambassador to US for Armenia?

As of my limited knowledge cutoff date in September 2021, the Ambassador of the Republic of Armenia to the United States was Varuzhan Nersesyan. However, it is possible that there has been a change in the ambassadorial position since then.

To obtain the most accurate and up-to-date information, you can check the official website of the Embassy of Armenia in the United States or the website of the Armenian Ministry of Foreign Affairs.
