Yes, you do need to be a American Citizen and you need a passport to go to Vietnam. Go and talk to a travel agent near you Your travel agent also can help you to apply for a Visa to go to Vietnam.

green card is fine. You need reentry permit to come back US. Travel agency will tell and help you to apply all the critical documentation before you travel and purchase the ticket.
