Federal prosecutors in Texas have reached a civil settlement with Infosys, an Indian outsourcing company, over charges that it misused temporary visas to bring Indian technology workers to the United States, justice officials said. In an investigation started in February 2011, prosecutors have examined whether Infosys systematically used short-term visitor visas to bring software programmers and technology engineers from India to work in American companies, instead of more costly H-1B visas, deceiving immigration authorities and undercutting wages for American workers. Infosys has said it set aside $35 million for the settlement, which will be announced on Wednesday.
