The widow of Kuchibhotla, who was killed in February this year in an alleged hate crime can stay in the US for now after the intervention of an influential lawmaker.
The Indian Consul-General in Houston, Anupam Ray, met Grillot, 24, and conveyed the message on behalf of Indian External Affairs Minister Sushma Swaraj.
Kuchibhotla's former boss described him as the kind of job candidate that every hiring manager wanted on his team.
Srinivas Kuchibhotla, 32, was killed and Alok Madasani, another Indian of the same age, was injured in the shooting by the navy veteran Adam Purinton.
His last rites were performed at the cremation ground in Jubilee Hills on Tuesday.
At the vigil, Madasani recalled how Kuchibhotla never complained about picking him up and driving him to work for six months.
Other customers present at the time of incident said that Purinton was tossing ethnic slurs at the two men.
The Federal Bureau of Investigation (FBI) is probing whether the shooting could be a possible hate crime.
US lawmakers publicly denounced the killing of an Indian engineer in an apparent hate crime in Kansas City, saying there is no place for these senseless acts of violence in the country.
The Trump administration has dismissed as "absurd" any correlation between Trump's remarks on immigrants and the Kansas shooting incident that resulted in the death of an Indian engineer.
The wife of the late Indian engineer Srinivas Kuchibhotla, Sunayana Dumala said reports of bias in the US make minorities afraid as she questioned "do we belong here".
