Right, But I was thinking to write the invitation letter on my own addressed to high commision and write a separate letter from both of us addressed to my parents saying we look forward to their visit and such (informal letter); and they can use submit that letter with the application too? Does this make sense? Having 2 letters? What you think.Bryanna said:You can write a joint Invitation Letter.... you should include details about yourself and your spouse (as stated in the CIC link) + provide the necessary supporting documents
