WASHINGTON, Feb 26 (PTI) : An American employee of Infosys has filed a case against the company accusing it of visa and tax fraud.

In his complaint filed before an Alabama Court early this week, one Jack Palmer said he worked for Infosys "as a Principal - Enterprise Solutions" since August 2008.

In his-13 page complaint, he alleged that Infosys sent lower level and unskilled foreigners to the US to work in full-time positions at its customer sites in direct violation of immigration laws.

He claimed that Infosys was paying these employees in India for full-time work in the United States without withholding federal or state income taxes, and overbilled customers for the labor costs of these employees.

After the federal government restricted the H-1B program, in 2009, Palmer claimed, he was sent to Bangalore, for planning meetings.

Asked for its reaction, the Infosys declined to comment. "We are unable to comment as the matter is under litigation," Infosys spokesperson said over phone from Bangalore.
