I would like my mom to visit me in Canada where I will be studying. She then decided to apply for her Canadian visa, and one of the document that they asked her to show was Purpose of travel which includes showing documents such as a flight ticket departing Canada or a travel itinerary. Does this mean she needs to purchase a ticket before getting a visa. I already write her a letter of invitation stating she will be staying with me in my suite while she is here and the length of her time in Canada which is two weeks. Is there something else I can show instead of a ticket. what should I do?
