Do I need insurance to apply for an American visa?

American B2 tourist visa is applied at the American Consulate in China. This is a formal document without any additional commercial terms/products.

B2 visa is the holder's permit to legally enter the United States: you can apply for B-2 visa for sightseeing, entertainment, visiting relatives and friends, medical treatment, attending conferences, exhibitions and handling personal affairs in the United States.
