Mphasis stock fell despite the company saying in a stock exchange filing that it didn't expect the visa charge to impact its financials or operations. The firm, which has offices in several US states, said it has only made around 130 new applications for H-1B visas this year. It added that it has reduced its reliance on the program through local hiring, acquisitions, and partnerships, and said that it plans to address any challenges on this front with AI tools.
