Indian software services exporter Infosys has inaugurated a new technology and innovation hub, its fourth in the USA. The new hub in Raleigh, North Carolina, will help Infosys work more closely with clients in fields such as Machine Learning, Artificial Intelligence, user experience and advanced digital technologies, including big data and Cloud. The hub will train and retrain Infosys clients' employees in the technologies required to help American businesses accelerate their digital transformations. Bangalore-headquartered Infosys already has technology hubs in Indianapolis, Indiana as well as in Hartford, Connecticut and Providence, Rhode Island. Infosys began a drive to set up technology hubs and increase the hiring of Americans after the Donald Trump administration began tightening visa requirements and resorting to other protectionist measures. The company claims that since 2017 it has hired more than 4,700 American employees, and aims to increase that number to 10,000.
