To cut cumbersome security clearance for expats in telecom companies, the Department of Telecommunications (DoT) is likely to ask the home ministry to raise the validity of work permits to 5 years from 1 year now. "In a recent meeting it was pointed out that the Ministry of Home Affairs is taking an abnormal period to grant security clearance in respect of foreign personnel. It was decided that we may request the ministry to increase the security clearance period from 1 year to 5 years," an official source said. Vodafone Managing Director and Chief Executive Marten Pieters, Uninor's Nominated Chief Executive Officer Morten Karlsen Sorby, Sistema Shyam Teleservices CEO Dmitry Shukov are some of the prominent foreign faces working in India.
