My son who is a Canadian citizen has married a woman from Japan and he has returned to Canada and she is still in Japan pending their application approval for her to join him once this has been approved. She has her portion of the application package and he has his. There is a question on her application that she is unable to answer. It is - which Visa office will be processing the application? Can you suggest how she is to correctly answer this as we know that no question can be left blank?
