Hello guys,
My mom has multiple entry visa to Canada. She had visited us couple of times in the past and last time in March 2018 from India and then she visited my sister in USA for two months and now she is back to Canada but this time they didn't stamp anything on her passport at airport. So how long she can stay ? Six months from now or six months from March 2018 ? Do Canadian boarder officers use electronic data for exit and entry now, kindly advice ?
