"We will stand with you, whatever you need," he said. Responding to this Grillot said, "I look forward to being able to go meet everybody."
Mr Grillot and his family are invited to India as soon as he is able to travel, according to a news release from the University of Kansas Health System.
Mr Grillot was shot in hand last week when 51-year-old American navy veteran Adam Purinton, prior to opening fire, uttered racial slurs and yelled "get out of my country" at the two Indian victims.
Indian engineer Srinivas Kuchibhotla, 32, was killed while another Indian man and his colleague Alok Madasani was critically injured.
In a video from his hospital bed, Mr Grillot had said: "I was just doing what anyone should have done for another human being. It's not about where he was from or his ethnicity."
