Hello, I am trying to help my mom to fill IMM5257 form for visitors visa. She is retired person from 1999, so the form ask you to put dates “to” and “from” how I can put word present or forever for date “to”? In the end, the form need to be validated. Is it appropriate if I leave this column blank, and after validation to write word “present” with pen or need to put the same date when you fill the form? Thank you very much!
