Been there, so for those who haven't worked in India...there, you have to keep your home license (CAA/FAA/JAA issued) valid, in order for them to validate and give you a 6mos FATA(validation/permit)...this is for expats only...fyi. In China, they give you a Chinese License, same as in Vietnam, Singapore and mostly the rest of the world....not just a validation. Hope this helps answer few of your inquiries..
Nice flight
