My sister from India has two daughters one in USA and one in Canada. She holds multiple entry visas for 10 years to both countries. She is planning to visit her daughters in Summer of this year and wants to plan the trip.
Q1: Can she stay in Canada for 6 months with one daughter as a visitor and then move to USA for another 6 months to be with the other daughter?
Q2: If she visits in between Canada and US within first 6 months what rules apply to her duration of stay in either countries?
