How can visit united states now ?
Get some money, buy a plane ticket & voila !
with a Passport, or Visa.... as well as an itinerary
Plane ticket with Passport or Visa
As long as you can get the appropriate visa it should be pretty pat. No visa no trip though.
Sorry you can't come now...United States is closed for the holiday. Try next year though.
Get a student visa and you are golden.
