Jay Palmer had filed the lawsuit in Alabama in February 2011, saying he had been punished and sidelined by Infosys executives after he reported witnessing widespread visa fraud.
While his lawsuit was dismissed last year by a federal judge, it spurred the federal investigation into Infosys' visa procedures. Palmer said the case has continued to dominate his life ever since he filed the lawsuit.
The paper quoting people familiar with the case reported Palmer could receive as much as USD five million from the payment Infosys will make to the federal government, under a provision of federal false claims law.
In one of the largest immigration fines ever, the second largest software exporter from India today agreed to pay USD 34 million to settle the visa row but denied visa fraud.
