I would like to know the rules and exceptions of a temporary visitors visa? You see my mother is visiting us from the Philippines with a multiple entry visa and I know she is allowed to stay for 6 months in Vancouver because there is no date on the stamp. But we visited the US for a week and came back. My question is does this renew her stay for another 6 months? Or does her original entry still in effect? I'm quite confused on how the rules and exceptions plays out. Thank you in advance on all replies
