I had visited USA 5 years ago, my B1/B2 visa expires in 2020, I got the visa while I was working for my former company which I quit 3 years ago. Since my visa is still valid, so I guess I have no visa issues. And now I would like to re-enter a week later for my vacation. I have couple of questions, please someone clarify
I have been wandering, I have travel itinerary, valid passport, b1/b2 visa, I booked a hotel for 4 weeks but I don't no anybody (personal contacts) in USA.
Do I need to have somebody contact information to enter USA?
Does the immigration officer at airport request USA citizen contacts?
