Hi I need clarification if you guys can help me..my mom arrived 3 days ago in toronto pearson..and i checked her passport it has no arrival stamp or duration how long she can stay..but her passport on the page with the visa sticker..on the right top of it..it has handwritten date august 01.2018..her visa approved on august 10 2017..what is this mean? Is this mean she can stay until 1 year here? Its so frustrating ..her visa is PG1 multiple
