Indian govt declare some air bubble to travel, where they will allow foreign airlines to operate in Indian airport.
My parents have valid B1/B2 visa, can they travel in any foreign airlines?
As per my knowledge, the Vande Bharat special flight which was the only option to travel during lockdown in India, were allowing only GC, Citizen or valid work permit visa holder to travel from India to USA.
Is there any restriction for tourist visa holder in USA in corona time?
