The United States has announced it will provide employment authorisation cards to some non-immigrant categories, including those waiting for green cards, for five years, a move that would benefit thousands of Indians living in the country. According to a new study, more than 10.5 lakh Indians are in the queue for an employment-based Green Card and 4 lakh of them may die before they receive the much-sought-after legal document of permanent residency in the US.
