NEW DELHI: India has been in touch with the US government for extending the validity of visa of Indian nationals (H1B and other types of visa holders) who are stranded in the US due to the Covid-19 pandemic.Foreign secretary Harsh Shringla in his telephone conversation with US deputy secretary of state Stephen Biegun took up this issue, official sources said. If the employer in the US terminates the contract of an H1B holder employee, the employee needs to find new employment within 60 days to retain H1B status. Government sources clarified that there was no order as such from the US government asking employers to terminate services of H1B visa holders.Congress on Friday had urged the government to talk to the Trump administration to prevent job losses of Indians holding H-1B visa
