My parents have both US & Canada multiple entry Visitors Visa. They are currently in Canada. How many times can they travel between Canada & US?
Their total trip duration US + Canada is not more than 6 months.
We are currently planning to cross the border from Canada to US three times; 2 times at Niagara for a span of 2 days each time and then by flight into JFK, New York for a 3 month stay.
Is there an issue in this nature of travel?
Thank You in Advance.
