Juster, 62, is an old India hand who played a key role in the landmark Indo-US civil nuclear deal.
He would replace Richard Verma as the top American diplomat to India. The position has been lying vacant since January 20 after Verma resigned from the post with the swearing in of Donald Trump as the 45th President of the United States.
The latest development follows Juster's nomination confirmation which was on last Friday agreed by the powerful Senate Foreign Relations Committee by a voice vote, reflecting the bipartisan support his nomination has in the Congress.
Trump's senior adviser and daughter Ivanka Trump will be leading a high-powered American delegation of entrepreneurs to the GES, which will be inaugurated by Prime Minister Narendra Modi.
