Hi ... I want some information that I'm a spouse a principal applicant and we did our interview in the visa office and the officer told as I accept your case ,then after 2 days the ircc send as pre-arrival email ,but after a month they request me background/declaration form because I was in national service before 19 years I think they want to check my background . I am confident in my background but if they decide negative is it hurt the my spouse who is a principal applicant and our two kids?
