Ian Grillot was injured when he tried to intervene in the shooting by a Navy veteran targetting Indians at a bar in Olathe, Kansas last month.
Srinivas Kuchibhotla, 32, was killed and his colleague Alok Madasani was critically injured in the shooting.
Mr Grillot will be honoured as 'A True American Hero', at the 14th annual gala of India House Houston here on March 25.
"Without all the prayers and positive support from everybody, I wouldn't be doing as well as I am right now. It's been a blessing to be alive. I am looking forward to attend India House Gala event on March 25, in Houston, TX. You guys are wonderful and I thank you all for such a support," Mr Grillot said.
The annual Gala is the main fundraising event of the India House, with all proceeds going to the day-to-day community programmes and expansion of India House. "We are privileged to honour Ian Grillot at our biggest event of the year. We invite all Houstonians to come, celebrate Ian's true American spirit and support India House's annual fundraising event," said Jiten Agarwal, Board Member and 2017 Gala Chair of India House.
Guests of honour this year include many dignitaries including India's Ambassador to the US Navtej Sarna, former US Ambassador to India David Mulford, former US Assistant Secretary of State Nisha Biswal, Mayor Sylvester Turner, Harris County Judge Ed Emmett and Master Chef Vikas Khanna.
