I recently applied for my Sister to come and visit me in Canada. When we applied for her visa, we stated she would stay for 22 days. However, her visa was approved. But now we think she may remain for at least five and half months since I would use her help with our baby. When entering Canada, should I book her return ticket for 22 days or reserve it for the five and half months she is planning to stay? I am just wondering for when the officer asks. Thanks in advance.
