Border security wouldn't say one way or the other.
They sent me a link to their page I already read. The page says what can keep you out but does not really provide details.
They all tell me a DUI is very seriose. OK big deal is seriose here too. How long is the prohibition? They don't say. I was hoping for a more solid answer, but I guess al government is the same.
I think they want the money.
