I was Drafted at 18 for vietnam & when i got to vietnam, i walked off the battlefield, can i come visit usa ?

JImmy Carter declared amnesty for draft dodgers in Canada, but I don't know if deserters would be included. Chances are ,no one would even care, now, and there may be no record that is easily found . You might can check with the American emby, or hire a lawyer or some one to research it out.
