The tricolour, which stretches 153 by 102 feet, was created by entertainment businessman Monty Saiyed and has found place in Limca Book of Records in April this year.
His creation will feature at the two-day Vibrant India event to be held in Chicago on July 16 and 17 with performances from Bollywood actors and singers.
"The flag is a message of peace and unity. This is an occasion of unity where everybody should stand together and support the cause of the flag and take the honour of it," Saiyed, 35, said.
It took 15 days for seven Porbandar tailors, recruited by Saiyed, to sew this cotton flag.
After the Vibrant India event, the flag will be flown back to Navsari in Gujarat and could be used in other events in different Indian states.
"Next year, the flag will be used for the same purpose of peace and unity in different states in India," Saiyed said.
Saiyed, who is living in the United States since the age of seven, said his ancestors first came to India 1,100 years ago from Medina in Saudi Arabia, when King Siddhraj Jaysingh was the ruler settled in Navsari.
His family members also run a foundation called "Gandhi Peace Mission" in Gujarat for the last 7-8 years.
