This might be more directed at Canadians and others not living in the U.S. As a dumb teenager/young adult, I was convicted of dui(1986), marijuana possesion(1989), and dui once again in 1990. Can anyone tell me what effect these charges have on me entering the States? What can I do if these will prevent me from entering, such as pardons, etc. I'm not looking to immigrate or anything, just visiting. Am I outta luck? Thanks for help.
