I am going to New York for first stop, and followed by Chicago and Florida for a business trip. I am departing from Hong Kong.
I already have my 10 years B2 visa ready. Any advices before travelling to the US? Like any other documents to present (other than my hotel bookings, travel itinerary and return flight ticket) once I touch down on the US soil?
I also heard that we need to apply for some kind of "permit" before depart to US, yes?
Let me know if there were any related topics under this sub-forum and I'm sorry if this question is repeated.
Thank you in adv!
