Your travel authorization has been approved and you are authorized to travel to the United States under the Visa Waiver Program.
So I've been accepted onto the Visa Waiver Program/ESTA. I've been to America before on a separate ESTA in 2015 with no problems. But this time I plan to take a trip into Canada for a few days with my America friend in his car while I'm over in America.
Flying in and out of JFK on both ends of my overall trip, trip is 3 weeks long overall, just wondering will I have to get another visa to enter Canada? Will I have to pay a fee for reentry to USA, or get another visa to enter back into the USA?
