A recent Forbes report on billionaire immigrants who started their careers in the US on an H-1B visa features only a handful of Indians. Among them is Raj Sardana, founder and CEO of Innova Solutions, who moved to the US for higher education, built a business from the ground up, and is now worth $2 billion.

Born in 1960 to Punjabi parents who migrated to India during the Partition of 1947, Sardana grew up in government housing in New Delhi. His family had no modern amenities—no heating, air conditioning, refrigerator, phone, TV, or car, according to HT.

“Despite our humble beginnings, my parents instilled the values of relentless hard work and found a way to provide quality education to me and my brother,” Sardana recalled in an interview with Authority Magazine.
