Thank you @canuck_in_uk for the reply. Do you know if i can drive to Niagara Falls Rainbow Bridge, have refusal from us entry and return with my car back to Canadian side to do landing ? I really don't want to walk the bridge with newborn child. I just don't know whether you can make u turn without actually entering US and whether you can wait in your car or park your car at the Canadian Border services? I checked all the posts here in this forum and not able to find someone who tried to do similar landing with a car. Thanks in advance.
