Tata Consultancy Services plans to open two computer services centres in the US in one of the biggest expansions by an Indian information technology outsourcing company in a developed market.

India’s largest computer services company, part of Tata Industries, said the first centre of 500-1000 people would open in Cincinnati, Ohio, by the end of this year or early next year, with the second to follow in late 2008 or early 2009 at an undisclosed location.
