I need to apply for family sponsorship visa for outland spouse but every time i try to download mandatory forms, i get the below error. I have even tried downloading acrobat reader DC as well as tried with the paid version of acrobat pro but cant get access to actual forms. I'd really appreciate if i could get any assistance for solving this issue. Thanks. Kubeir Kamal
