"Port of Entry letter" for US citizen with a Business Visa?
2 days before I get in a plane, someone has mentioned I need a "port of entry letter", along with my invitation letter, printed itinerary, passport, and visa... When I google that phrase, I see the need for that letter if I was going from India to the US as an Indian citizen. I will be going to Hyderabad.
Do I really need a "port of entry letter" along with all of these pieces of paper???
