Hello. I am permanent resident and my parents will apply for a visitors visa. In the purpose of the visit there are two options. One is tourism and the other is visit a family. They will do both things. If they declare that they want to "visit family" the application will require to add a letter of invitation, proof of relationship, the plane ticket, and the hotel booking. If they declare tourism, the application require less documents. Has anyone be in this situation? What should they declare? Thank you!
