Wanted to know which is the border closest to Ottawa, where I can apply for a TN status. This would be my first time. I want to be in and out with minimum hassle. Also if anyone has ever applied for TN status at a border close to Ottawa what their experience was like. Is it correct that you cannot apply for TN during weekends. Are immigration officers dealing with TN visas available 24 hours or are they available 9:00 to 5:00 only. Please advise...Thanks.
