It has been four months since I applied for a trip to Canada. Why haven't I signed it yet? Notify me to fill in the materials ten days ago. Please advise.

Generally speaking, the Canadian tourist visa is a two-week probation period. If you have been trying for four months, it will be really weird. First, make sure that the materials you submitted at that time are true. Secondly, if you are looking for an intermediary to apply for a tourist visa. Then you have to make sure when the travel agency will submit it to you and whether they are hiding anything from you.
