Q: was wondering if its just like how the airport works with traveling visa and how its obtained at the airport before boarding....so my question is..... do i have to go through US customs and obtain a visa at the greyhound bus station or something?
A: That's not a visa, you are talking about a Travellers Declaration Card. No, you don't have to fill one out, they are only distributed for flying. The average Land crossing of Canadians going to the US and back does not require any paperwork.
